Particle Theory and Pressure in Gases

5.15 explain how molecules in a gas have random motion and that they exert a force and hence a pressure on the walls of a container

5.20 explain, for a fixed amount of gas, the qualitative relationship between: • pressure and volume at constant temperature • pressure and Kelvin temperature at constant volume.

______________

5.21 use the relationship between the pressure and Kelvin temperature of a fixed mass of gas at constant volume:

p₁ / T₁ = p₂ / T₂

5.22 use the relationship between the pressure and volume of a fixed mass of gas at constant temperature:

p₁ V₁ = p₂V₂
