A student investigates the rate of cooling of hot water in a container which has a lid.
Plan an experiment which enables the student to investigate the effect of different starting temperatures on the rate of cooling.
The apparatus available includes:
- a beaker
- a measuring cylinder
- a supply of hot water
- a lid
In your plan:
- state any additional apparatus required
- explain briefly how to do the investigation
- state the key variables to keep constant
- draw a table, or tables, with column headings, to show how to display your readings (you are not required to enter any readings in the table)
- explain how to use your readings to reach a conclusion.
