An ideal gas A and a real gas B have their volumes increased from V to 2V under isothermal confition. The 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.
