Thermodynamics in JEE Main — FAQ

How should I approach JEE Main Thermodynamics?

Start with the First Law (ΔU = Q - W) and understand all 4 processes (isothermal, adiabatic, isobaric, isochoric) and their PV diagram shapes. Then learn Carnot cycle and engine efficiency. Practice numerical PV diagram area calculations.

Are Thermodynamics questions formulaic in JEE Main?

Mostly yes — Carnot efficiency, work done in processes, and specific heat calculations are direct formula applications. The tricky questions combine two processes or ask about entropy change.
