cools, it goes down the tube again. There is a scale on the
thermometer. The numbers show the temperature.

We measure temperature in degrees Celsius (°C). In
the Celsius scale, water freezes at 0°C and boils at 100°C.
Thermometers can show temperatures below zero degrees
Celsius. We use the word ‘minus’ for temperatures below zero.
For example, -6°C.
