Revise Gas Pressure & Temperature in Particle Model for GCSE Physics with 19 exam-style questions and 30 flashcards. This topic appears regularly enough that it should still be part of a steady revision cycle. It is section 2 of 12 in this topic. Focus on the labels, the relationships between parts, and the explanation that turns the diagram into an exam-ready answer.

📊 How Temperature Affects Gas Pressure

Gas pressure particle model showing particles moving randomly inside a container, colliding with walls to create pressure, with arrows showing force on walls and explanations of how to increase pressure

Figure 1: Gas particles colliding with container walls create pressure. More energy = harder and more frequent collisions = higher pressure.

KEY POINT: Gas pressure is caused by particles hitting container walls. Heat the gas → faster particles → more frequent AND harder collisions → pressure increases!
