States of Matter

Water becoming ice is an easy example of changes of state. But it's also air turning into liquids, solids turning into gases, and gases getting so hot they become plasmas that in future might propel spaceships around the solar system.

All matter, it turns out, can change its state into any other state: solid, liquid, gas, or plasma. Investigate the states of matter.
