0 °C (32 °F), is the exact temperature at which water changes
from a liquid to a solid (ice).

Conclusion
FOR ONLINE READING ONLY
This experiment verified that the freezing point of water is 0 °C
(32 °F), at which it changes from a liquid to a solid.

Boiling point of water

Water boils when it reaches a specific temperature. The boiling
point is the exact temperature at which a liquid (water) boils and
turns to water vapour. The boiling point is important because
it ensures safe drinking water. Some foods are cooked better

when the water has reached its boiling point.

Experiment 6: Investigating the boiling point of water

Aim: To demonstrate boiling point of water

Materials: Heat source (stove), water, saucepan and

thermometer

Note: Do not remove the thermometer from the water

while reading the temperature.

Procedure

1. Place the saucepan with water on the stove that is already

switched on.

2. Measure the temperature of the water as it begins to boil.

3. Continue measuring the temperature of the water until it
boils vigorously.

4. Record the results.
