Pressure and Volume

In this title we are going to explore how volume affects the pressure exerted by a gas.

We are going to do this by looking at a scenario of a volume of air in a container with a piston that can reduce the volume available to the gas. The user can interact with this by changing the volume of the gas. The gas is represented by a set of molecules that move and collide with the sides of the container and each other. The rate of collisions, the pressure and the temperature are monitored.

This e-scenario presents the concept in a highly visual and accessible way, allowing the student to explore the concept through interaction and observation. The underlying Physics is deliberately made clear, helping the student to develop an intuitive understanding of the ideas involved.

Finally, a closely related GCSE examination question is examined, allowing students to apply what they have discovered in the e-scenario to an examination situation.

The package is supplied as a PowerPoint presentation containing the teaching material and a link to the online e-scenario. The e-scenario runs in any WebGL-compatible browser, including Edge, Firefox and Safari.
