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?
Answer:

(“Am” is a linking verb, showing no action. This means we’re dealing with a subject complement and not a direct object.)

(“Have been” is a linking verb in this sentence, showing no action. “An accountant for many years” is, therefore, a subject complement and not a direct object.)
