Select the correct statement :

A

Internal energy of a real gas at a given temperature increases as the volume increases

B

Internal energy of an ideal gas at given temperature increase as the volume increases

C

Internal energy of an ideal gas molecules is not a function of temperature

D

The internal energy of a real gas at a constant temperature is independent of change in volume

Text Solution
