The state of matter is a deceptively simple concept. It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff ...

Matter can exist in three common states on Earth: solid, liquid and gas. This series explores how matter changes state and how we use matter in all states in our everyday lives. Excellent introductory ...

Before scientists discovered the new state of matter last week, we were basically all used to just three states of matter. After all, during our daily lives we encounter some variety of solids, ...
