Everything consists of matter. All matter consists of particles. If the particles are
closely packed so that they can only move a little bit, the substance is a solid.
If the particles are more loosely packed so that they can slide over each other,
the substance is a liquid.
Heating causes a solid to melt and change state from solid to liquid.
Cooling causes a liquid to solidify. For example water changes into ice.
