Heating and cooling experiment

This experiment will show how water reacts to extreme temperatures of hot and cold. The equipment you will need for this experiment include:

  • A small empty beaker
  • A bigger beaker with ice
  • A flask with coloured liquid, the tube with markings on it
  • A kettle

Method and observations:

  • Place the flask with coloured liquid in the small empty beaker
  • Pour the boiling water in the beaker and let it rest for a minute. You will see the level of liquid in the tube rising
  • Now remove the flask from the beaker and place it in the beaker with ice
  • Let it rest there and observe the level of the liquid in the tube falling as the liquid cools
