1. Molecule size negligible
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.
, KTG & THERMODYNAMICS – SHORT NOTES Class 11th
Charles law states that the pressure remaining constant, the volume
of a fixed amount of a gas varies directly with its absolute
temperature.
Pressure exerted by a mixture of non interacting gases is equal to the sum of their partial pressures. Hence,
for a mixture of n gases, the total pressure of the gas is given by

A particle speed probability distribution shows how the speeds of molecules are distributed for an ideal gas.
