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

View answer and explanation

Correct option: C

of B will be more than that of A

Option C is correct. The internal energy of a real gas (B) increases more than that of an ideal gas (A) under isothermal expansion because work is done against intermolecular forces in the real gas.
