The kinetic molecular theory states that all particles of matter are a. in the form of a gas. b. always in motion. c. very close together. d. compressible. (not a or c)

Option (B) is the correct answer.

Explanation:

Kinetic molecular theory states that all the particles present in a matter constantly move from one place to another.

This is because all particles have certain energy but this energy changes with change in temperature. The amount of energy will help in determining whether the matter is in solid, liquid or gaseous phase.

Therefore, by changing the temperature, a change in phase will occur.
