Vedclass · Answer

(C) For an ideal gas,the internal energy depends only on temperature. Since the process is isothermal (temperature remains constant),the change in internal energy for the ideal gas $A$ is zero.For a real gas $B$,the internal energy depends on both temperature and volume because of the presence of intermolecular forces. When the volume of a real gas increases,work must be done against these attractive intermolecular forces,which leads to an increase in the internal energy of the system.Therefore,the increase in internal energy of the real gas $B$ is greater than that of the ideal gas $A$.

An ideal gas $A$ and a real gas $B$ have their volumes increased from $V$ to $2V$ under isothermal conditions. The increase in internal energy
