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.

"the periodic table is arranged in order of atomic number."

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
