Solid, liquid, gas ^^
For example, if you have an ice cube you have a solid piece of matter, but if you heat it up it melts and then it's liquid, and after getting hot enough it evaporates and even though you can't see it it's still there, but as a gas.
By the way, what's this have to do with Spanish?
