CSEC Physics · 1990 · Paper 2 · Question 4(b)(iii)

Figure 6 shows an apparatus used to investigate how the volume of a fixed mass of air varies with temperature.

Theory suggests that the volume of the gas becomes zero at a certain temperature. What is the value of this temperature?

This question uses a figure or table from the paper — you'll see it when you practise.
