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?
