Consider the diagram. which postulate of the kinetic-molecular theory best describes the event in the diagram?
a. most of the volume of a gas is empty space.
b. all collisions between particles are perfectly elastic.
c. there is no force of attraction or repulsion between gas particles.
d. the average kinetic energy of particles depends only on temperature.

Answer : Option B) All collisions between particles are perfectly elastic.

Explanation : Gases consits of molecules which are compressible because the gas particles which have a small volume compared to the container.

The collisions are perfectly elastic because when gases are left alone in a container they don't seem to lose energy and do not spontaneously get converted into a liquid, also energy is not lost during collisions.

In the diagram given above one can interpret that the gaseous molecules are in random motion inside the container and when they collide with other molecule of gas they do not lose energy. Therefore, this shows perfectly elastic collisions.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
