How gas particles produce pressure
How gas particles produce pressure
Gas particles move rapidly and randomly, travelling in straight lines between collisions. When a particle collides with a wall and rebounds, its velocity changes, so the wall exerts a force on the particle and the particle exerts an equal and opposite force on the wall.
Step-by-step lessons on Edexcel GCSE Physics 14.3 Gas pressure and temperature. Each one builds up to exam-style questions. Master the required practical work and core equations early, since both papers can draw on content and maths skills from across the whole specification.
