A gas thermometer contains a fixed mass of gas in a sealed rigid vessel. The table shows the pressure of the gas at different temperatures.
| Temperature in °C | Pressure in kPa |
|---|---|
| 20 | 100 |
| 40 | 107 |
| 60 | 114 |
| 80 | 121 |
Describe how the pressure changes as the temperature increases. Use data from the table.
Explain why the pressure changes as the temperature increases.
