[00:00:06][snorts] Good morning.

[00:00:19]Good morning, warriors. Good morning. Am I audible?

[00:00:24][snorts] Good morning.

[00:00:37]>> [snorts] >> Good morning based warriors. Good morning.

[00:00:55]So >> [snorts] [clears throat] >> Are you guys ready for that?

[00:01:21][snorts] >> [clears throat] >> Jay Shri present. Good morning. Good morning.

[00:01:40][snorts] So good morning. First [snorts] date 15 25 27 next 10 days we have to study a Last sixth chapter book. One of the easiest chapter [snorts] library [snorts] Buy now free state [clears throat] >> [snorts] >> Chapter six.

[00:03:28]Very very important.

[00:03:30][snorts] Okay. Right.

[00:03:51]Okay. [snorts] Good morning. Yes. Good morning.

[00:04:01][clears throat] Right. We will started.

[00:04:29][snorts] All right. First question. State boils.

[00:04:38][snorts] At a given temperature. At a given temperature.

[00:05:09]At the given temperature, [snorts] the volume occupied by a fixed mass of gas is inversely proportional to its pressure.

[00:05:31][snorts] wrong or you're in Shabba.

[00:05:51]Gas.

[00:06:03]Sorry.

[00:06:05]temperature.

[00:06:07]For example, [cough and clears throat] [snorts] regular [snorts] [snorts] AC Cold [snorts] early morning.

[00:07:19]Simple [snorts] dusty early morning.

[00:07:47]>> [snorts] >> For example, 28° 1 kg volume is inversely proportional.

[00:08:14]inversely proportional pressure increase [clears throat] pressure increase volume Pressure increase volume.

[00:08:46]If the pressure increases, volume decreases.

[00:08:51]Pressure decrease volume increases.

[00:08:56]V is directly proportional to 1.

[00:09:03]V is equal to K into 1 by P input P V= K equation ideal gas equation rightcept [snorts] oriented question.

[00:09:49]teacher maybe even though I'm not a teacher.

[00:10:02]training 99 [snorts] easiest way.

[00:10:35]>> [snorts] >> sticky wall. Water bottles in the law. Answer questions.

[00:11:20]Batch 2022. Batch 2022. Last batch 23 23 starting [snorts] 23. Middle school 23 23 August 23 August 23 August [snorts] concept concept is very very easy right name two item that can serve as a model for tire pressure in summer and winter. Tire pressure in summer and winter.

[00:12:38]Temperature increase.

[00:12:41]Temperature increases.

[00:12:56]foreign for a fixed mass of gas. If the temperature increases, pressure also increases.

[00:13:12]temperature increase for example temperature increase Temperature in case pressure tire will burst Because UAV, UAE, Dubai, [snorts] you fill a car tire completely full of air on the pressure on the hottest day of summer, right? Full of the tire cannot change its shape and volume. But when winter comes the pressure inside the tire reduces because the temperature decreases Temperature decrease.

[00:15:05]temperature and pressure or [snorts] T is directly proportional to temperature is directly proportional to pressure. T is equal to K. Tal Kalper Temperature increase increase.

[00:15:52]First temperature.

[00:16:09]You can try it in your home.

[00:16:16]Boiled egg. A glass bottle is taken. Put some pieces of cotton inside the bottle and light them. Then place a boiled egg at the mouth of the bottle. The temperature inside the bottle increases because of fire. Raising the pressure.

[00:16:33]When the flame goes out, pressure goes out. Air inside cools and the pressure drops. This causes the egg to be sucked into the bottle.

[00:16:52]Okay. Right. Super. Next question.

[00:16:56]Mathematical expression relates the gas volume gas volume.

[00:17:07]P V is equal to NRT. PVL.

[00:17:12]P Val.

[00:17:15]pressure.

[00:17:19]Ve is number of moles. R is gas constant. R is gas constant. Pressure volume temperature number of moles gas constant. Clear right equation. Important question by the [snorts] okay right. What are ideal gases? In what way real gas differ from ideal gas?

[00:17:46]Ideal gas.

[00:17:49]Ideal gas is defined as one in which all collision between atoms and molecules are perfectly elastic.

[00:18:01]Ideate fake priority.

[00:18:30]Because real gas easion between atoms and molecules are perfectly elastic.

[00:19:16]Perfectly elastic.

[00:19:30]It will get settled.

[00:19:35]For example, velocity Calm down.

[00:20:20]Gasd perfectly elastic and in which there is no inter intermolecular attractive force.

[00:20:42]There is no attractive force.

[00:20:48]There will be no attractive forces.

[00:20:57]Right. Okay. for PV= PVL form.

[00:21:11]Okay.

[00:21:15]Realm realm expect gases obey all gas law under all condition.

[00:21:34]All gas law under all condition of temperature and pressure.

[00:21:48]Idle gas only at low temperature. Low temperature gas proportional inversely proportional high temperature high pressure volume occupied by the molecule. Volume occupied by the molecule is negligible compared to the total volume of the gas.

[00:22:36]volume occupied by the molecule is negligible compared to the total volume of the gas.

[00:22:47]For example, volumetal volume occupied by molecule is negligible compared to total volume.

[00:23:46]You don't need to consider it.

[00:23:59]Okay.

[00:24:03]volume by the molecule is not negligible compared to the total volume of the gas. So total volume of the gas force of attraction among the molecule is negligible.

[00:24:51]The force of attraction among the molecule is negligible.

[00:24:59]Is not negligible at all temperature and pressure.

[00:25:03]It is not negligible because oxygen oxygen hospital.

[00:25:14]So oxygen is a gasp.

[00:25:24]So gasle Gas.

[00:25:33]Gasu molecule. Gas molecules.

[00:25:51]CNG liqufied petroleum gas compressive [snorts] attractive attractive force.

[00:26:19]Yeah, right. [snorts] Vandrol gas with a= liquified equation, right?

[00:26:44]Suppose there is a tiny sticky area.

[00:26:50]tiny sticky area on the wall of a container of a gas. molecule hitting this area permanently.

[00:27:04]Is the pressure greater or less on the ordinary area.

[00:27:20]If the gas molecules stick on the walls of the container then the number of molecules striking the wall of the container decreases and decrease the number of gas molecule in the same volume container decreases the pressure in the bottle pressure.

[00:27:38]For example, it will force the container.

[00:28:01]All the molecules are forcing outwards.

[00:28:11]wall outer body. They are forcing it.

[00:28:21][snorts] attack.

[00:29:01]pressure on the sticky wall pressure.

[00:29:08]pressure decrease. So hence the pressure decreases.

[00:29:19]>> [snorts] >> A B C D E A B C D water bottles are kept under water during the summer. Water bottles.

[00:29:48]Cool drinks bottle carbonated water during summer.

[00:30:02]Any idea what will happen? Any idea? So nth chapter nth chapter.

[00:30:16]N chapter.

[00:30:19]Nap.

[00:30:33]What happened?

[00:30:42]Right.

[00:30:44]Single digit single digit right bottle water bottle.

[00:31:15]water.

[00:31:25]Temperature increase.

[00:31:30]If the temperature increases, temperature increases, pressure.

[00:31:37]Sorry, temperature increase. Pressure increase. Temperature increases.

[00:31:42]Pressure also increases. Pressure also increases. Temperature increase.

[00:31:47]Pressure increase.

[00:31:50][snorts] Saturday for example.

[00:32:13]So pressure increase all the way the pressure hits the wall of the bottle.

[00:32:58]11.

[00:33:03]Seriously? Yes. Because teachers keeping.

[00:33:28]So definite we will be improved.

[00:33:34]experience.

[00:33:42]Captain temperature increase.

[00:34:00]Soap they have infused the gas to the liquid.

[00:34:12]Gas liquid dissolve.

[00:34:16]Dissolve.

[00:34:18]They have dissolved the dissolved the gas. [snorts] Oh my god.

[00:34:29]Right.

[00:34:33]Dissolved.

[00:34:38]High pressure.

[00:34:55]Pepsi.

[00:35:06]The taste will not be good. Taste will not be good.

[00:35:12]Dissolved carbon dioxide.

[00:35:19]Temperature increases.

[00:35:23]Solubility temperature increase.

[00:35:52]up to this there will be a gap full because so gas can be compressed Temperature student writing. Okay. Good. Good. Good.

[00:36:28]Super. Good.

[00:36:32]The solubility of the gas in water is likely to decrease.

[00:36:38]The solubility likely to decrease since rise in temperature increase pressure become too high the glass will not be able to withstand. So the bottle may explode. To avoid this we have to keep the bottle under the water.

[00:37:10]Right. So, uh we will stop here. Okay.

[00:37:14]We'll stop it here and we will see the next part. We will see it in the next part.

[00:37:22]We will stop it here. Okay. So, we will meet in the next class. Okay.

[00:37:31]Tada!
