Key Stage 3
Meaning
Depositing is an exothermic process in which a gas turns directly into a solid without going through the liquid state.
- Noun: Deposition
- Verb: To deposit
- Present Participle: Depositing
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. |
Key Stage 4
Meaning
Depositing is an exothermic physical change in which a gas turns into a solid without going through a liquid phase.
About Deposition
- Depositing happens when the particles in a gas form bonds that hold them together in fixed positions as they lose potential energy.
- Deposition is an endothermic process, which means it needs to absorb energy to take place.
- Deposition is a physical change, which means it is reversible and does not produce new chemicals.
- Substances may deposit depending on the pressure and temperature around them.
- Frost is caused by the deposition of water vapour in very low temperatures.
