Question 13

Plan an experiment to investigate how the surface area of water exposed to the air affects the rate of cooling of hot water.

Write a plan for the experiment, including:

  • the apparatus needed
  • what you would measure
  • the variables you would keep the same to ensure the comparison is a fair test
  • instructions for carrying out the experiment
  • how you would present your results
  • how you would use your readings to reach a conclusion.

You may draw a diagram if it helps to explain your plan.
