An ideal gas A and a real gas B have their volumes increases from `V to 2V` under isothermal condtitions. The increase in internal energy

Options

A. will be same in both A and B
B. will be zero in both the gases
C. of B will be more than that of A
D. of A will be more than that of B

Answer

B

Explanation

In an isothermal change, the temperature as well as internal energy remains constant. Hence the increase in internal energy `(DeltaU)` will be zero in both gases.
