A student investigated the change in temperature when oils of different specific heat capacities were heated.
She set up the apparatus shown in Figure 5.
This is the method used.
1. Put 25 g of oil into a boiling tube.
2. Pour 100 ml of water into a beaker and heat it with a Bunsen burner.
3. When the water is boiling, put the boiling tube into the beaker.
4. When the temperature of the oil reaches 30 °C, heat for a further 30 seconds and record the rise in temperature.
5. Repeat with different oils.
6. Repeat the whole investigation.
Name two pieces of apparatus the student used that are not shown in Figure 5 suggest one improvement to the students method ki
