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 it quickly evaporates from your hands so you don't need to dry them.
