A student uses a syringe connected to a digital pressure sensor to investigate how the pressure of a fixed mass of gas varies with its volume at constant temperature.
Table 1 shows the obtained results.

Describe what happens to the pressure of the gas when the volume of the gas is reduced to one-third of its original value (for example, from 30 cm330\text{ cm}^330 cm3 to 10 cm310\text{ cm}^310 cm3).
The temperature of the gas inside the syringe was kept constant during the experiment. Which two of the following properties of the gas particles would change if the temperature increased?
Practise AQA GCSE Physics Particle model and pressure with exam-style questions for Foundation and Higher tier. 12 questions covering Particle motion in gases, Pressure in gases (physics only), and Increasing the pressure of a gas (physics only) (HT only), matched to the AQA GCSE Physics (8463) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
