Revise AQA GCSE Physics 3.3.1 Particle motion in gases with the question bank, lessons, revision guides, and flashcards.
The molecules of a gas are in constant random motion. The temperature of the gas is related to the average kinetic energy of the molecules. • Changing the temperature of a gas, held at constant volume, changes the pressure exerted by the gas. • Students should be able to: explain how the motion of the molecules in a gas is related to both its temperature and its pressure • explain qualitatively the relation between the temperature of a gas and its pressure at constant volume.
