Water is an example of matter that exists in three states: as a gas over 100°C, as a liquid between 1-99°C, and as a solid below 0°C. It is made of hydrogen and oxygen, has volume and mass, and is odorless, colorless, and tasteless. Water changes state through heating and cooling, melting when heated as a solid, evaporating when heated as a liquid, freezing when cooled as a liquid, and condensing when cooled as a gas.

and mass.

3. It is made from hydrogen
and oxygen.

4. Water does not smell.
It’s Odorless.

5. Water does not have colour.
It’s colourless.

6. Water has no taste.
It’s tasteless.

7. Water exists in three states:

8. Water is in a gas state at
temperatures of over 100ºC

9. When water is a gas it
expands to occupy as much
space as possible.

10. Water is in a liquid state
between 1ºC and 99ºC.

11. When water is in a liquid
state it takes the shape of
the container.

12. Water is in a solid state at
temperatures below 0ºC.

13. When water is solid, it
expands to occupy more space.
It has bigger volume

14. When you heat solid water it
changes into liquid.
Water melts.

15. When you heat liquid water it
changes into water vapour.
Water evaporates.

16. When you cool liquid water, it
changes into a solid.
Water freezes.

17. When you cool water vapour,
it changes into a liquid.
Water condenses.
