About Depositing
- Only a few materials change directly from a gas into a solid. Carbon Dioxide is an example of a gas that does not become a liquid but will undergo deposition.
- Depositing is a reversible process. When a gas deposits into a solid you can sublime that solid back into a gas.
- Cooling a gas will cause it to deposit into a solid.

| The particles in the gas slow down until they are slow enough that forces between the particles start to hold them together in fixed positions. The particles become stuck in fixed positions and a regular arrangement which makes the state a solid. |
