Can a solid change into a gas?
Factory smoke is a good representation of a solid changing into a gas because it shows how solid fuel can be combusted to produce gaseous smoke.

Sure, a solid can change into a gas. This is called sublimation.
One example of a substance that sublimes is dry ice. Dry ice is a solid form of carbon dioxide. When you heat dry ice, it sublimates, which means it changes directly from a solid to a gas without becoming a liquid in between.
Another example of sublimation is mothballs. Mothballs are made of a substance called naphthalene, which sublimates at room temperature. This is why you can sometimes see a cloud of white powder around mothballs.
Sublimation is a cool phenomenon that happens when a solid changes directly into a gas. There are a few different substances that can sublime, and you can see it happen in everyday life.
- Sublimation is the opposite of deposition, which is when a gas changes directly into a solid.
- Sublimation is also used in freeze-drying, which is a way to preserve food. In freeze-drying, the food is first frozen and then the water is sublimated. This leaves the food dry and dehydrated.
