My son, second grade, is doing states of matter. We were trying to help him label different examples for solid, liquids, and gasses. In his science textbook, it mentions that you can’t see a gas and that steam is a liquid because it’s just water suspended in the air, but on his worksheet, by a different source, has fog and smoke as an example of a gas. I’ve always thought of smoke as a gas on a base level. I understand that there are particles being suspended in the air that you can see, but can someone help the states of matter so I can help my son with his homework.

If it sticks together and keeps its shape, it’s a solid.
If it will spread out to fill its container but stays stuck together, it’s a liquid.
If it doesn’t stick together and just spreads out to fill its container, it’s a gas.
Before anyone starts coming at me with exceptions, the kid is 2nd grade, this is specific enough.
