3. STATES OF WATER

Lola has something to say!

As Lola has said, there are 3 STATES OF WATER:
- LIQUID, like the water in seas, rivers, oceans and the water we drink.
- SOLID, like snow, ice and hailstones.
- And GAS, like water vapour.

But... Can water change from one state to another?

Let´s play a game to discover it. Follow the instructions on the webpage to play:



As you have seen, water can change from one state to another:

a) When liquid water is very cold, it freezes and becomes a solid. this is SOLIDIFICATION.

b) When ice or snow gets warm, it becomes liquid water. This is MELTING.

c) When liquid water gets hot, it becomes water vapour. This is EVAPORATION.

d) When water vapour gets cold, it becomes liquid water. This is CONDENSATION.
