Answer 1

The inversion temperature in thermodynamics and cryogenics is the critical temperature below which a non-ideal gas (all gases in reality) that is expanding at constant enthalpy will experience a temperature decrease, and above which will experience a temperature increase

Answer 2

The van der Waals equation of state approaches the ideal gas law PV=nRT as the values of theseconstants approach zero. Theconstant a provides a correction for the intermolecular forces.Constant b is a correction for finite molecular size and its value is the volume of one mole of the atoms or molecules.
