Answer: Collisions between gas particles are inelastic.
Explanation: Kinetic Molecular Theory explains the basic relation between the temperature and the speed of the gaseous molecule . From this theory itself, ideal gas equation was born.
the incorrect postulates among the given is that the 'Collisions between gas particles are inelastic' because during collision, the gas molecules collide with one another as well as with the walls of the container .
Thus there is no loss of kinetic energy in the collision phenomenon .
It is also correctly given that Gas particles are small and spherical with an insignificant volume and the motion of gas particles is constant and random.
