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.

14.3 Gas pressure and temperature Lesson

  3. /14.3 Gas pressure and temperature

Step-by-step lessons 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 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.
