Assertion: In free expansion of a gas inside an aidabatic chamber Q, W and `DeltaU` all are zero.
Reason: In such an expansion `pprop1/V`.

In isothermal free expansion of an ideal gas find the value of q and DeltaU.

Assertion : In free expansion of an ideal gas, the entropy increases. Reason : Entropy increases in all natural processes.

Assertion : Work done during free expansion of an ideal gas whether reversible or irreversible is positive. Reason : During free expansion, external pressure is always less than the pressure of the system.

(A): If an ideal gas expands in vacuum in an insulated chamber, DeltaQ,DeltaU,DeltaW all are zero (R ): Temperature of gas remains constant

Assertion:- During adiabatic expansion of an ideal gas, temperature falls but entropy remains constant. Reason:- During adiabatic expansion, work is done by the gas using a part of internal energy and no heat exchange teakes place the system and the surrounding.
