Why does matter (solid, liquid gas) change phases?

You know that in a solid, the molecules wiggle in place. In a liquid, they move more and slide over each other. In a gas, the molecules bounce around and move very fast. The difference between the phases is a difference in how the molecules move.
Therefore, if you want to make matter change phase, you have to make its molecules move differently.
How do you make a molecule move faster? It is simple. Remember that heat is the energy of moving molecules. To make a molecule move faster you have to heat it.
How do you make a molecule move more slowly? To make a molecule move more slowly, you have to take heat away.

Phase change: The physical change of matter from one phase to another. A phase change takes place because the particles of a substance gain or lose energy, causing them to change their motion.

Evolution, according to Darwin. Soon it become a Monkey and then a Human. Sounds like a lot of "Gas" to me, but, everyone has their opinion.
