In the case of real gases, the equation of state, PV = RT (where P, V and T are respectively the pressure, volume and absolute temperature), is strictly satisfied only if corrections are applied to the measured pressure P and the measured volume V. The corrections for P and V arise respectively due to
  • kinetic energy of molecules and collision of molecules
  • size of molecules and expansion of the container
  • expansion of the container and intermolecular attraction
  • intermolecular attraction and the size of molecules
