2. Molecule is assumed to be hard sphere and all collision elastic
3. No interaction among molecules => Total Energy = K.E + P.E = K.E
4. Collision time is negligible
5. Effect of Gravity on molecule is neglected
6. Real gases obeys Ideal gas law PV=nRT at very high T and very low P
, Boyle’s law states that the pressure of a fixed amount of a gas varies
inversely with the volume if the temperature is maintained constant.
Charles law states that the pressure remaining constant, the volume of
a fixed amount of a gas varies directly with its absolute temperature.
