- In the Metric System (SI), we measure temperature in degrees Celsius.
- There are special temperatures on the temperature scales called Freezing Points and Boiling Points.
- Freezing Point: the temperature where water freezes and becomes a solid.
- Boiling Point: the temperature where water boils and evaporates (becomes a gas).
Temperature is used to measure how hot or cold something is, which is related to how much thermal energy it has.
Metric System (SI): Celsius
Freezing Point = 0° Celsius
Boiling Point = 100° Celsius
