  • question_answer
    An ideal gas A and a real gas B have their volumes increased from V to 2 V under isothermal conditions. The increase in internal energy [CBSE PMT 1993; JIPMER 2001, 02]

    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

    Correct Answer: C

    Solution :

               No change in the internal energy of ideal gas but for real gas internal energy increases because work is done against intermolecular forces.
