Kinetic Theory Of Gases

Question 1

What is the kinetic theory of gases?

Answer 1

1. The time of collision is negligible.
2. The collision between the molecules of a gas and its container is always elastic.
3. Gravitational effect is negligible on gas molecules.
4. The motion of gas molecules is random.
5. Between collisions, molecules move in a straight line at constant speed.
6. The size of the actual molecule is negligible compared to the molecular separation.
7. All the molecules of a particular gas are equal.
8. A gas consists of a very large number of molecules each with mass M moving randomly.

Question 2

State the law of equipartition of energy.

Answer 2

It states that in a dynamic system in thermal equilibrium, the total energy of the system is shared equally by all the degrees of freedom.
