Free notes + solved JEE problems for this lesson: https://rankdeterminant.com/go/yt-phy... All lessons of this unit:    • JEE 2027 Physics | Unit 8 Thermodynamics   Four JEE Main-level thermodynamics problems from the unit problem bank, solved step by step: the first law with the right signs (a gas compressed while losing heat, delta U = -600 J), Mayer's relation and gamma from Cv = 20, a heat engine of 30% efficiency that rejects 700 J, and the temperature rise when air is compressed adiabatically to double pressure, with the traps students fall into.
