NEET/JEE-PHYSICS TRICKS - THERMODYNAMIC - SIGN CONVENSION

[00:00:02]sign convention sign convention For example, system and the gas are the same equal.

[00:00:29]gas system gas For example, system system For example, heat H E A T heat heat gas molecules gas molecules heat again heat expansion gas system heat heat gas gas do work expansion expansion gas gas system heat produced more collides gas collides heat produced which is heat temperature system temperature rise temperature rise temperature increase internal only depends on temperature.

[00:01:56]Internal energy at the increase of working life internal energy I don't know you number increase of 70 but I want to be alone positive heat not system could I do positive heat given to the system heat given to the system given to system or gas working life and I want to add a positive element heat not gas expand out of expand out of do work up work done by the system work done work done by system I love you guys working life in the work done I don't know anything temperature rise out of the sun and the temperature rise out of any kind of energy increase out of internal energy increases working life and I want to increase 70 opposite and I don't know how much decreases and the negative condition I don't know anything in one and one zero same money in a trick I don't know anything I don't know anything follow thank you.
