Postulate 1gases consist of tiny particles (atoms of molecules)Postulate 2These particles are so small compared to the distances between them that the volume of the individual particles can be assumed to be zeroPostulate 3The particles are in constant random motion, colliding with the walls of the container. These collisions with the walls cause the pressure exerted by the gas.Postulate 4The particles are assumed not to attract or to repel each other.Postulate 5The average kinetic energy of the gas particles is directly proportional to the Kelvin temperature of the gas (Charles' Law)

1)Gases contain large number of tiny and discrete particles called molecules
2)Gas molecules are very much apart from each other
3)The molecules move randomly in all directions with high velocities
4)The collisions between gas molecules of perfectly elastic
5)pressure exerted by a gas is due to collisions of molecules made on the walls of the vessel
6)KE is directly proportional to the temperature
7)Molecules are electrically Netural and do not have attractions or repulsions between them
8)Molecular motions are unaffected by gravity
