Answer 2

$\sf{\underline{Kinetic\:theory\:of\:gases:}}$

Kinetic theory of gases is based on the molecules picture of matter. According to which:

$\hookrightarrow$ A given amount of gas is a mixture of very large number of identical molecules of the order of Avogadro's number.

$\hookrightarrow$ The molecules are moving randomly in all directions.

$\hookrightarrow$ At ordinary temperature and pressure, the size of the molecules is very small as compared to the distances between them.

$\hookrightarrow$ Thus, the interaction between them is negligible.

$\hookrightarrow$ Hence, they move according to Newton's laws of motion.

$\hookrightarrow$ The molecules do not exert any force of attraction or repulsion on each other, except during collisions.

$\hookrightarrow$ The collision of molecules against each other or with the walls of the container are perfectly elastic.

$\hookrightarrow$ Such that the momentum and the kinetic energy of the molecules are conserved during collisions, though their velocities change.
