Derive expression for the pressure exerted by an ideal gas on basis of kinetic theory of gases.

Answered by admin @ 20/08/2021

ACCORDING TO KINETIC THEORY OF GASES :

A) Gases are composed of very tiny molecules and they have large numbers of molecules

B) The gas molecules are elastic

C) The gas molecules are negligible in size compared to their containers.

D) Their thermal motions are random.

Based on these facts the formulae for ideal gas is :
