Describe what is meant by absolute zero, in terms of the particles of a substance.
A student says that a gas can be cooled to a temperature of −300 ∘C-300\ ^{\circ}\text{C}−300 ∘C.
Explain why the student is wrong.
108 exam-style questions on Edexcel GCSE Physics 14.3 Gas pressure and temperature, covering 14.3.1 Gas pressure and particle motion, 14.3.2 Temperature and pressure at constant volume, 14.3.3 Absolute zero and the kelvin scale, 14.3.4 Compressing and expanding gases, 14.3.5 Volume and pressure at constant temperature, and 14.3.6 Doing work on a gas. Each one has a worked solution and a mark scheme showing where the marks go.
