The BEC is all about atoms that are closer and less energetic than atoms in a solid. A water molecule is made up of two hydrogen (H) atoms and one oxygen (O) atom.

If you give a liquid water molecule enough energy, it escapes the liquid phase and becomes a gas.

The extra energy allows the molecules to change states.

If you place a glass of liquid water on a table, it will just sit there.

If you place a glass of water in a vacuum chamber and lower the pressure, you can begin to watch the water boil and the water molecules move to a gas phase.

You are able to smell the volatile compounds that are mixed in the air around you. If energy is added (increasing the temperature) or if energy is taken away (freezing something), you can create a physical change.

Changing the pressure of a system is another way to create a physical change.

Solids are often hard, liquids fill containers, and gases surround us in the air. For example, when the temperature of a system goes up, the matter in the system becomes more excited and active.

If enough energy is pushed into a system, a phase change may occur as the matter moves to a more active state. When the temperature of the water goes up, the molecules get more excited and bounce around a lot more.

Plasma was a new idea when it was identified by William Crookes in 1879.

We also like to talk about the Bose-Einstein condensate (BEC).
