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.
