States of Matter
There are three primary states of matter: solid, liquid, and gas.
Solids are the lowest energy form of matter on Earth. Solids are generally tightly packed molecules that are held together in such a way that they can not change their position. The atoms in a solid can wiggle and jiggle (vibrate) but they can not move from one place to another. The typical characteristics that solids tend to have are that they keep their shape unless they are broken and they do not flow.
Liquids have loose, stringy bonds between molecules that hold molecules together but allow them some flexibility. Liquids will assume the shape of the container that holds it.
Gases have no bonds between the molecules. Gases can be squished (compressed), and pure gases all behave the same way. (We’re going to learn more about this with the Ideal Gas Law.)
