There are four common states of matter (or phases) in the universe: solid, liquid, gas, and plasma.
The state of matter affects a substance's properties. Examples of those properties include density, viscosity (how well it flows), malleability (how easy it is to bend), and conductivity. Changes between states of matter are often reversible.
