Elaborate on the changes in molecular motion of particles as they change from solid to liquid to gas. a) as the phase changes occur, the freedom of motion of the particles increases. b) as the phase changes occur, the freedom of motion of the particles decreases. c) as the phase changes occur, the freedom of motion of the particles compresses. d) as the phase changes occur, the freedom of motion of the particles is constant.

A)As the phase changes occur, the freedom of motion of the particles increases.

Explanation:

In solids the particles are tightly packed the freedom of motion of the particles in solids are very limited. Liquids and less tightly packed and in gases the particles move about freely. Thus as the phase transition happens from solids, to liquids to gases, the freedom of motion of the particles increases.

the answer would be b i believe
