How does the kinetic energy of a substance's particles in the liquid phase compare to their kinetic energy in the gas phase?

Question

australopithecus · Answer

A compound in the gas phase has more kinetic energy than that of something in the liquid phase. Gas molecules are spaced out and can bounce around a ton they take up more volume. Whereas Liquid molecules are compact relative to gas molecules they dont have much room to move around, because of steric hindrance. 


Heat is just kinetic energy, so something that is extremely hot, is made up of matter that is has a lot of kinetic energy.

Now when you boil water (which is a liquid) what happens? It turns into a gas.
