[00:02:00]Sahayshree Rethanya Iniya, Jeeva Rose, Krishna Kumar Shivani, good.

[00:02:20]Result and it's a Zion.

[00:02:23]Zion result and it's a good good good.

[00:02:25]Kanishka Good.

[00:02:28]Okay, good evening Basangala. Welcome to the session.

[00:02:32]First chapter Right.

[00:03:00]Oh, science and English and 95 marks, very good. 488, okay, very good. Arshita Tulasi Good. Sashmita, good good good good, very good.

[00:03:12]Very good.

[00:03:13]Super You all have become ninth standard students. I'm already ninth standard done.

[00:03:27]Result and that you have to super and that Kovergini 491 and that mark where the level of getting the king here.

[00:03:36]Daily one of the class Monday to Friday income. Nate miss I think no problem in the regular class.

[00:03:42]5 to 6 or 6 to 7 one of the daily very good and very awesome and that can be very good class income.

[00:03:52]>> I need to find a good class in it cool.

[00:04:05]Right, super.

[00:04:06]495 uh uh uh uh uh uh uh uh Another level that Okay, right right. Harshita Govardhani super good. Jerry bar Last class in a bottle now going to go back. Number measure that out there number is really a proper girl. Number room in a line up with a pretty line in the car I'm going to be number bottle for a solid Liquid and a gas not in there. I think I'm going to matter in there in the matter of the mission of the I don't know what I'm going to do with my last class.

[00:04:38]I don't know what I'm going to Yeah Yeah Yeah Saturday or Friday I don't know I'm not sure. Saturday Friday Lena Thursday but I don't think it's Friday.

[00:04:45]Friday I'm a Friday May 1 Thursday but I don't think it's Friday. Yeah, correct. Yes.

[00:04:53]I don't know what I'm going to do with my voice low or high.

[00:04:57]Wait for me to watch check money in a person in there.

[00:05:07]Okay, but I was going to increase I don't know what I was going to do with my voice.

[00:05:11]90 standard 15 I don't know what I'm going to do with my 90 day. I don't know what I'm going to do with my result.

[00:05:17]Result when you need a lot of 90 standard longer I don't know what I'm going to do. I don't know what I'm going to do with my 90 day.

[00:05:25]Yes, yes, super good good good.

[00:05:29]I don't know what I'm going to do. Very good. I don't know what I'm going to do with my 90 day super. Good.

[00:05:35]Right.

[00:05:36]Okay, right right right.

[00:05:41]I don't know what I'm going to do with my 90 day super good good good good good good good good. I don't know what I'm going to do with my 90 I don't know what I'm going to do with my 90 I don't know what I'm going to do with my of particles particles about the number two right now. Mhm.

[00:05:55]Right. Change in state.

[00:06:04]Change in state.

[00:06:09]Ready?

[00:06:18]from one state to another state.

[00:06:22]state solid, liquid, gas solid liquid gas in the solid liquid gas in the solid liquid gas solid liquid or liquid gas gas solid gas liquid period period detail solid liquid interesting interesting If you are ready, put a >> If you are ready put a fire in chat.

[00:07:47]Yes.

[00:07:49]Solid to gas.

[00:07:51]Good guess. Park la. Solidification ah?

[00:08:05]Super. Ready.

[00:08:07]First solid to gas.

[00:08:10]Solid to liquid liquid to gas.

[00:08:15]Solid to liquid liquid to gas.

[00:08:18]Liquid to gas.

[00:08:23]Yeah.

[00:08:25]Solid.

[00:08:28]Solid.

[00:08:33]I don't know what to put liquid.

[00:08:38]Liquid.

[00:08:40]There we go.

[00:08:44]I did gas.

[00:08:46]Gas while you.

[00:08:56]One minute.

[00:09:16]So leave me every way to go. Just tell me what you want for two minutes.

[00:09:28]How was your leave?

[00:09:52]>> 1 minute 1 minute >> Oh, not be silly and make a mark. Okay, right.

[00:12:07]Mhm, [snorts] like Coimbatore meet up Right.

[00:12:22]9th grade master video file. 9th grade master video file ready by the way Number two minute master start button with a first minute and start button with a good turn Okay, very good. Very good. Very good.

[00:12:39]Olympiad sitting there. Good. Very good.

[00:12:47]solid liquid gas Right.

[00:12:52]solid learning liquid to matter in there I did the reverse liquid in the solid matter in there.

[00:13:01]liquid gas and matter in there gas liquid and matter in there there I did the reverse there. solid gas and matter in there gas and solid and matter in there Right. Yeah. If you Talk about Right.

[00:13:24]Right. Come on. Come on. Come on.

[00:13:27]Oh, that one come out there. Yeah. Okay, right. Right. Oh, really?

[00:13:31]Okay, right.

[00:13:33]Solid and the liquid.

[00:13:35]Solid and the liquid and water.

[00:13:44]Solid to liquid is called melting.

[00:13:49]Melting. Solid to liquid to be anything.

[00:13:52]Melting. Solid and Liquid and gas and water. Liquid and gas and water and water vapor and water. About that anything. Water and water vapor and water and water and water.

[00:14:04]Water becomes water vapor. Water water vapor and water and water and water.

[00:14:10]Water water vapor and water and water.

[00:14:12]Evaporation. Evaporate out of the oven and the evaporation. Evaporation.

[00:14:27]Really? Evaporation. Really?

[00:14:30]Right.

[00:14:31]Solid and gas and water.

[00:14:34]I don't know what a solid what a solid I think of the Direct gas boiling and boiling is a process but conversion beta evaporation of the other meaning of the solid and of the other meaning of the beta.

[00:14:55]Water and water and water and water.

[00:15:03]Solid and gas and water and water.

[00:15:06]Very good. Very good. Yeah, SDA. I don't know what you are learning good good good but I don't know what I had all that. Sublimation and I don't know what I had all that. What a solid gas I don't know what you are going to do and I don't know what you are solid. I don't know what you are going to do and I don't know what you are going to do and I don't know what camphor very good Sudam naphthalene ball very good naphthalene ball camphor right up camphor Sudam naphthalene ball camphor sublimation kind of best example solid learning gas sublimation Tamil padam gamal up in salon in a sublimation Tamil padam gamal Rita padam gamal super Sudam camphor naphthalene ball naphthalene ball Vishal solid liquid and matter the liquid gas and matter gas and the thermal solid and the matter to be ready to go back gas and the solid and the matter now solidification gas solid and the matter gas and the solid and the matter and the liquid and the matter direct matter and the matter and the slow process and the matter Rita slow process and the matter solid and the gas liquid and the matter that gas and the solid that can matter gas and the solid that can matter gas and the good good good good good good good and the matter good and the matter and the liquid and the >> Freezing right out of bed and freezing freeze ponder that right out right out What cha It also agrees Karthik and I don't really Kathi Karthik Kathi da kathi I do gas liquid and marinate I doubt water vapor liquid and marinate condensation right out condensation condensation and I do Danny mega girl in LA cool with you mega girl in LA Nina I'm looking at it Nina I don't know my little girl and I might So that is called condensation right out in the condensation I do better condensation three out of the condensation condensation three out of freezing the terminal where I do very good freezing the terminal where I do in the condensation gas in the liquid I do better condensation and I do better right out condensation and if we do that that we do number detail back up first time melting up in the end of the melting the process now in the up in the back up three out melting the process now in the right out melting the end of the solid to liquid solid to liquid solid to liquid and I do better I see water and marinate and I do better melting up a melting Korea best example in the solid liquid and marinate melting and I do liquid and I do better terminal liquid and I do better solid gas out of the solid and liquid. Solid liquid and water that could be the melting At the boiling. Boiling.

[00:19:27]So that I don't want to natural boiling the process with a lot and I don't want to evaporation. Boiling boiling is called. Heating number school but then I'm a and the process of the moment. I'm going to get in the evaporation and I got it.

[00:19:46]Evaporation.

[00:19:54]I will have a lot of water.

[00:19:58]Steam and water.

[00:20:02]Evaporation and I got it. Boiling.

[00:20:15]I think condensation.

[00:20:17]Condensation and I got it and I got the condensation and I got it. Gas to liquid. I don't want to condensation and I got it. Gas and liquid and water. I got gas. Liquid and water. I got a lot of liquid and water. I got it. I got a lot of liquid and water for example but I don't want to natural. I don't want to natural gas and I don't want to chemistry. I don't want to natural gas and I don't want to petrol and I don't want to natural gas and I don't want to petrol.

[00:20:39]I don't want to natural gas and I don't want petrol diesel kerosene and I don't want to natural gas and I don't want to petrol. Do you know where we are getting it? I don't want to natural gas and I don't want to petrol and I don't want to natural gas.

[00:20:49]I don't want to natural gas and I don't want to petrol and I don't want to natural gas.

[00:20:52]Any idea but I don't want to natural gas.

[00:20:57]I don't want to natural gas and I don't want to petrol and I don't want to natural gas and I don't want to petrol.

[00:21:01]Crude oil very good very good oil and oil and oil and oil.

[00:21:05]Crude oil and crude oil and crude oil and oil. I don't want to natural gas and I don't want to petrol and I don't want to natural gas.

[00:21:10]in the crude oil right out crude oil Iran Israel us countries get it out in the crude oil oil Madrid oil in it would be good in the inner that so in the inner that one guy in the very good and heat tank heat so in the inner heat so you have to go with the heat and go for example and the heat and go for example either heat go in the inner over temperature for example I know the degree Celsius to go I know the degree Celsius petrol vapor very good distillation very good very good it is called distillation I don't know the fractional distillation I don't know right right it is called distillation so I'm a 500 degree Celsius example right out 500 degree Celsius petrol in the vapor out there out I'm a vapor cool petrol I'm a cool vapor boil vapor cool vapor cool condensation vapor cool process to build that Condensation and it could be the other number Condensation is over condensation and it is number or gas liquid or matter that right a gas liquid or matter that I do but you have been there 500 degrees Celsius the vapor level stop by the chair I mean I don't know what I'm going to get 700 degrees Celsius I put 700 degrees Celsius in the middle of the diesel with It is what example kind of I'm not giving the actual value it is just example of the period So I do 700 degrees Celsius In the middle of the over temperature over there number over oil petrol diesel kerosene white petrol in the middle of one and a number over temperature and it will come I will go over temperature in the vapor collect money I will go over cool money I will be cool money I will be cool money I will be cool money I will be cool under portal of a petrol diesel It will be able to connect it I've been there I will go over to school petrol diesel and I I will go over to school petrol diesel and I condensation gas liquid or matter that I remember gas liquid or matter that I remember I can get it So I do freezing freezing but I don't know freezing and I know what is freezing later freezing and I know that freezing is called liquid to solid later freezing and I know that liquid and the solid later freezing and I know that liquid to solid liquid and the solid or matter that I can get a lot liquid liquid and the solid or matter that for example if I don't know summer season and I I don't know what I'm going to do in the fridge there ice cubes are being later and I know what I'm going to do liquid I'm going to put in the matter refrigerator fridge there freezer which is a freezer out there I don't know what I'm going to do I don't know what I'm going to do freezer I don't know what I'm going to do I don't know what I'm going So freezer or the temperature is different freezer and I know what I'm going to do liquid and I know what I'm going solid or matter water and there ice cubes or ice tea or matter that I don't know ice or matter that I don't know it is liquid to solid and it will be in there I don't know what I'm going to do I don't know what I'm going to do I don't know what I'm going to >> Nitrogen, nitrogen, nitrogen liquid nitrogen liquid nitrogen.

[00:25:23]Liquid nitrogen liquid nitrogen.

[00:25:27]It is liquid temperature water nitrogen is a gas.

[00:25:40]Body spray body Body spray up around the spray cool.

[00:25:55]You know what the liquid? And the liquid expand out of temperature.

[00:26:00]So I did that we should temperature but that might. So I enter and there. Gas and I cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool cool.

[00:26:19]Gas cool cool cool cool and the liquid and the liquid and the liquid.

[00:26:25]The detail everything is normal. A gas cool but I don't know what kind of gas but you know what kind of gas but you know what kind of gas but you know what kind of gas but you. Let us do on try.

[00:26:40]I'm going to get an empty bottle.

[00:26:41]What do you get an empty bottle? What do you get?

[00:26:43]What do you get an empty bottle? What do you get an empty bottle? What do you get an empty bottle? Let us do this.

[00:26:48]Experiment. Try and find out. Next class I'm going to get an empty one. What do you get an empty bottle? What do you get an empty bottle? What do you get an empty bottle empty bottle empty bottle freezer freezer freezer 24 hours cupboard TV liquid one or two drops nitrogen mixture Try putting butter in it may happen. Try class freezer water bottle transparent water bottle fridge fridge bucket experiment example fridge Okay.

[00:28:20]liquid solid liquid to solid effect of temperature temperature cool heat boiling freezing condensation temperature temperature temperature temperature Temperature increase ponder in a lot.

[00:29:15]Is this two same or different? You want to render better same or different?

[00:29:19]You want to render better same or different?

[00:29:23]Are these two same or different?

[00:29:41]Daily now that nine standard class evening 5:00 to 6:00 6:00 to 7:00.

[00:29:47]You know you got different. What is the different?

[00:29:50]What is the different? Temperature and a heat and a net.

[00:29:53]Temperature and a heat and a net.

[00:30:11]Heat is hotness. Uh.

[00:30:23]Heat is a kind of energy. That's good answer. Good.

[00:30:28]Temperature have cold also. Okay.

[00:30:34]>> [laughter] >> Okay.

[00:30:37]Okay, right, right. Many of you should have with you as well. I doubt it. Heat.

[00:30:43]Heat again.

[00:30:53]I love you. It is the energy.

[00:30:57]It is a energy. It is a energy.

[00:31:01]And I love you. It is a energy.

[00:31:03]It is a energy.

[00:31:06]Later, but temperature is a measurement.

[00:31:11]Temperature is a measurement.

[00:31:18]I love you. Yeah.

[00:31:26]Temperature energy or I love you.

[00:31:28]Measurement.

[00:31:30]I love you.

[00:31:32]I love you. Heat in the water bottle.

[00:31:36]So that I can up in the water suit.

[00:31:39]weapon That is heat. I love you. So that in the bottle of the water bottle. I love you.

[00:31:58]I love you. That is called temperature.

[00:32:01]Temperature is a measure of Temperature is a measure of or the temperature is a degree of hotness or coldness.

[00:32:09]I love you.

[00:32:11]I love you.

[00:32:16]temperature temperature So yeah, this is temperature. I love you. It is a energy.

[00:32:26]I love you.

[00:32:30]I love you.

[00:32:33]Effect of temperature. I love you.

[00:32:38]temperature >> Increases motion of a particles.

[00:33:11]Tell me, what happens to water?

[00:33:14]It will start giving bubbles.

[00:33:30]Temperature going to be not going to increase the motion of the particle.

[00:34:10]Whenever the temperature increases motion of the particle increases.

[00:34:27]I'm going to cool it okay.

[00:34:33]Silent and okay and again.

[00:34:52]solid increase temperature effect of temperature temperature right temperature particles of motion temperature reduce particles It will become freezes very good become freezes right I think the pressure I will come in the bottle It is a 1 L water bottle.

[00:35:43]It is a 1 L water bottle.

[00:35:45]water bottle How much amount of water we can fill in this bottle?

[00:35:58]the bottle 1 L bottle 1 L of water fill the water bottle 1 L of liquid water 1 L of 1 L of liquid 1 L of liquid 1 L bottle How many liter of gas fill the water bottle?

[00:36:24]Tell me now. How many liters of gas can be filled?

[00:36:28]How many liter There is no specification, right? In the bottle order It depends upon the strength of this bottle.

[00:36:58]Gas little over gas or little over So gas on little over every every pressure up pressure I look at the way they affect our pressure. It happens only it acts only on gases.

[00:37:53]pressure order pressure But gas to change for the volume.

[00:38:20]Gas can be compressed.

[00:38:22]Helps convert gas to liquid.

[00:38:33]What did I get in the last class? LPG LPG but the question you asked get there.

[00:38:41]LPG but the only guy get in the last class question.

[00:38:43]LPG but he LPG but he only guy get in there. Yes.

[00:38:54]LPG Liquefied petroleum gas.

[00:39:00]Liquefied What gas and a liquid and a matter again?

[00:39:09]By angle What gas and a liquid and Liquid Particles comes closer.

[00:39:39]Particles Right out. Right.

[00:39:46]That's good.

[00:39:49]If you get in the matter what square shape container in the corner there I think I might not pressure That is Number cylinder with a shape actually with a right angle.

[00:40:14]Number cylinder with a shape You know how to get in the matter with a right angle and a right angle.

[00:40:20]in the gas even ship gas gas So tanker cylindrical high pressure effect avoid the pressure cylindrical petrol petrol petrol cylindrical and over >> audio petrol lorry audio oval shape Yeah, no. Danny in the bottle in the bottle in the bottle It is not a lorry.

[00:42:26]Let us consider like in the lorry lorry in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle in the bottle It will create lot of pressure. So, other way curved shape orange corner Danny Dango Danny Danny Danny oval Yeah, dude. square shape Danny liquid oval They will be like this. oval oval lorry lorry oval in the lorry lorry Danny lorry lorry in the lorry oval in the gas in the gas in the auto in the gas in the auto in the lorry in the gas in the gas in the lorry in the round white color in the gas in the round in the round pressure force in the video in the force in the force pressure in the related in the force in the force in the force in the force in the area For example in the board in the board there So now look at the force.

[00:44:28]pressure in the area and I could get it right out. force along with the area other pressure pressure in the area there force by area that pressure right out pressure is equal to force by area by pressure pressure I don't know but I think in the correct I don't know I'm a sharp I don't know the pressure.

[00:45:14]I don't know.

[00:45:19]pressure I don't know but I think I don't know.

[00:45:29]I don't right That's it. That's it.

[00:45:42]So I first lesson We are going to study the book back question.

[00:45:50]book back questions 10th standard video master I don't I don't >> 9th standard guy for the ocean 10th standard super for the many narrow and lucky super right Okay. Ta-ta. Bye-bye. If you can't, then who can?

[00:46:33]Ta-ta. Bye-bye.
