Chemistry homework help! 4 different substances in the 3 states of matter

For my chemistry homework there's a question that asks to "List four different substances in each of the three states of matter." In the reading it explains what a substance is (a particular matter with a definite fixed composition) and I know that the 3 states of matter are solid, liquid, and gas. There's nothing in the reading about any substances in the states of matter! Please help me?

Solids Diamond, Steel. gold, silver

Liquids Alcohol, water, benzene, acetone

Gases Oxygen, CO2, Helium, SO2

well, not going to do your homework for you, but look into these substances and you should find enough to understand what you need:

aluminium

mercury

ice

copper


sugar


carbon (diamond)

wax
