Answer:
Option A,D
Explanation:
(a) According to a postulate of the kinetic theory of gases, a collision between the molecules as well as with the wall of a container is perfectly elastic in nature.
(b) lf a gas molecule of man 'm' moving with speed 'u' collide to the wall of the container, the change in momentum is $\triangle$p= -2mu.Therefore heavier molecules will transfer more momentum to the wall as there will be greater change in the momentum of the colliding gas molecule. However, this was not postulated in the kinetic theory of Gases.
(c) According to Maxwell-Boltzmann's distribution of molecular speed, very few molecules have either very t ist or very low speeds. Most of the molecules move in a specific
intermediate speed range.
(d) According to the kinetic theory of gases, a gas molecule moves in a straight line unless it collides with another molecular or to the wall of the container and a change in momentum is observed only after collision
