A) internal pressure
B) inter molecular attraction
C) both and
D) temperature correction
Correct Answer: B
Solution :
For the explanation of behaviour of real gas van der Waal made correction in the ideal gas equation\[(PV=nRT)\]. He added\[\frac{a}{{{V}^{2}}}\]to pressure value to correct it. The correction was necessary due to intermolecular attractive forces which exist between the molecules appearing on surface.
