(b)

Under isothermal conditions, there is no change in internal energy

An ideal gas A and a real gas B have their volumes increased from V to 2V under isothermal confition. Th​​​​e increase in internal energy?
Answer- As we know that for isothermal process change in internal energy will be zero (delta U=0). So answer "B" is correct .(will be zero in both the gases).

The correct ans is (c) .since A is An ideal gas  nd B is a real gas. The behavior of both the gases would be different. Since for ideal gas ,under isithermal  condition, internal energy remain constant. Hence U of gas A must be less than that of B.
