Respuesta :

For a real gas to approach the properties of an ideal gas, the pressure should be low, the attraction between the molecules should be high and temperature should be high.

  • An ideal gas is defined as a gas that obeys gas laws at all pressure and temperature conditions. Ideal gases have velocity as well as mass. They have no volume.
  • The ideal gas law is the equation of the state of a hypothetical ideal gas, also called the general gas equation : pV=nRT

       where,  p= pressure

                    V= volume

                    n= number of moles

                    R= ideal gas constant

                    T= temperature

  • When molecules are almost in contact and for ideal gas the assumption is that there are negligible attractive forces between gas molecules.
  • Real gases show ideal behaviour when conditions of temperature and pressure are such that the intermolecular forces are practically negligible.This can only happen at very low pressure and very high temperature.
