CAPE Chemistry Unit 1 · 2017 · Question 2(a)

An experiment investigated the effect of temperature on gas volume. Observations were made on 0.100 moles of a gas at atmospheric pressure as temperature varied. Figure 1 shows seven readings of gas temperature measured by a thermometer, and the corresponding gas volumes.

Present the data provided above, as well as the temperature T(K), in a tabular format.

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