JEE tips

Revise Thermal equilibrium and the concept of temperature, zeroth law of thermodynamics with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to Thermal equilibrium and the concept of temperature, zeroth law of thermodynamics and reattempt after 48 hours
Revise Heat, work and internal energy with a one-page formula sheet before attempting mixed tests
After each practice set, log mistakes specific to Heat, work and internal energy and reattempt after 48 hours

Common trap

Students often rush Thermal equilibrium and the concept of temperature, zeroth law of thermodynamics questions without checking units, sign conventions, or boundary conditions — always verify assumptions before calculating.

Q1PhysicsUnit 8: Thermodynamics

The amount of work done by the gas system in increasing the volume of 10 mols of an ideal gas from one litre to 20 litres at

0^{0}

C will be

Q2PhysicsUnit 8: Thermodynamics

Assertion In an ideal thermodynamically reversible process, the energy from work performed by or on the system would be maximized, and that from heat would be minimized. Reason A reversible process is a process whose direction can be "reversed" by inducing infinitesimal changes to some property of the system via its surroundings, while not increasing entropy.
