Key Stage 2
Meaning
Evaporating is when a liquid turns into a gas.
- Noun: Evaporation
- Verb: To evaporate
- Present Participle: Evaporating
 |
| A liquid will evaporate to become a gas. |
About Evaporating
- Heating a liquid will cause it to evaporate into a gas.
- Evaporation is a reversible process. When a liquid evaporates into a gas you can condense that gas back into a liquid.
- You may have seen these evaporating:
- Water
- Hand Gel
Examples
 |
 |
| When water is boiling the liquid evaporates turning into a gas. Eventually all the liquid will be gone and the room will be filled with water vapour. | When you use Hand Gel the liquid quickly evaporates from your hands so you don't need to dry them. |
Key Stage 3
Meaning
Evaporating is an endothermic process in which a liquid turns into a gas.
About Evaporating
- Evaporation is a reversible process. When a liquid evaporates into a gas you can condense that gas back into a liquid.
- Heating a liquid will cause it to evaporate more quickly into a gas.

| The particles in the liquid move faster until they are moving fast enough that they break the bonds holding the particles together. The particles become free to move anywhere which makes the state a gas. |
