This question is about the behaviour of gas particles according to the kinetic theory of matter.
Explain how cooling a sample of gas (reducing its temperature) inside a rigid, sealed container affects the pressure of the gas. In your explanation, refer to the motion of the gas particles and their collisions with the container walls.
A compressed gas cylinder contains a fixed mass of nitrogen gas at a constant temperature. The gas has a volume of 0.045 m3 and a pressure of 360,000 Pa360,000\text{ Pa}360,000 Pa.
Calculate the constant for this gas. Use the equation:
pressure×volume=constant \text{pressure} \times \text{volume} = \text{constant} pressure×volume=constant29 exam-style questions on OCR GCSE Physics The particle model. Each one has a worked solution and a mark scheme showing where the marks go.
