- Water is a kind of liquid at room temperature
- Water is a kind of substance
- Freezing means matter / a substance changes from a liquid into a solid by decreasing heat energy
- So, water will change from a liquid to a solid by decreasing heat energy

- Water will change from a liquid to a solid by decreasing heat energy
- Temperature is a measure of heat energy
- So, water will change from a liquid to a solid by decreasing the temperature

So, water will change from a liquid to a solid by decreasing the temperature
