Learning objectives
What the syllabus expects you to be able to do.
- 2.1.3.1Explain with particles how the pressure of a fixed mass of gas changes when its temperature changes at constant volume, or its volume changes at constant temperature.
- 2.1.3.2Convert between kelvin and degrees Celsius using T (K) = θ (°C) + 273.
- 2.1.3.3Supplement: use pV = constant for a fixed mass of gas at constant temperature, including its graph.
