van der waals real gas act as an ideal gas at which

van der Waals’ real gas, act as an ideal gas, at which condition?

A. High temperature, low pressure

B. Low temperature, high pressure

C. High temperature, high pressure

D. Low temperature, low pressure

Answer : High temperature, low pressure

Solution :
At higher temperature and low pressure real gas acts as an ideal gas and obey $$pV = nRT$$ relation.
