For real gases, the Van der Waals equation of state introduces correction factors for both the volume and pressure of the gas. The correction for volume is due to:
1
elastic collisions of gas molecules.
2
finite volume of gas molecules.
3
gravitational pull-on gas molecules.
4
electrostatic forces between gas molecules.
