Homework Help: Chemistry

As a substance goes from a solid to a liquid, the particles
move further apart?

duh

For many substances, yes. It depends on the density of the solid/liquid. What does happen, is that in solids atoms are mostly bound in a crystal arrangement, and not free to move except in a vibrational mode. In a liquid, the atoms can move about.
