Heating and Cooling

Temperature is a measure of how hot or cold something or someone is.

                    

We measure temperature with a thermometer and the units of measurement are Celsius ( °C ).

Your normal body temperature is 37°C.

Water freezes when it reaches a temperature of 0°C.

Water boils when it reaches a temperature of 100°C.

Materials change either to a different state (solid, liquid, gas) or to a different material altogether when we heat or cool them.

Can you decide what different material or state (solid, liquid, gas) we will end up with if we heat or cool these materials?
