📊 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!
