Question

State any 6 assumptions on which kinetic theory of gases is based

Answer 1

Hint:
When collision occurs between two molecules, no energy is gained or lost.
A negligible space is occupied by the molecules of gas in a container.
These molecules always tend to follow linear motion.

Complete step by step answer:
The six assumptions of kinetic energy theory of gases are:
(a) A gas of a pure material consists of a large number of identical molecules.
(b) The molecules are always in a constant random motion.
(c) We can say that a gas molecule is an ideal particle.
(d) We can ignore the intermolecular forces.
(e) The collisions occurring are of less duration as compared to the time interval between two successive collisions and perfectly elastic hence ,conserving total momentum and kinetic energy.
(f) A gas molecule always travels in a straight line with the constant speed between two successive collisions.

Additional Information:
The ratio of space-volume to molecules is negligible.
At normal temperature and pressure no force of attraction is there on the molecules. when the temperature decreases and the pressure increases the force of attraction builds among the molecules.
Continuous motion of molecules is there as there are large gaps among the molecules.
The collisions which are perfectly elastic are a result of free movement.

Note:
Elastic collisions occur between molecules and walls.
Newton’s laws of motion are followed by all the molecules in certain gas samples .
If a gas sample is left undisturbed for a long time time, it eventually comes to a steady state.
