An ideal gas expands from an intial volume `V` into vacuume under isothermal conditions. For this process,

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:

For an ideal gas expanding adiabatically in vacuum,

Certain amount of heat supplied to an ideal gas under isothermal conditions will result in
