Boyle's Law — Pressure & Volume
Boyle's Law — Pressure & Volume is a free interactive simulation for GCSE Physics (Edexcel IGCSE 4PH1) in which students compress a gas using a piston and measure how pressure changes with volume at constant temperature. No login required — includes a self-marking quiz.
Aim: To investigate the relationship between the pressure and volume of a gas at constant temperature.
Data Table
| # | Pressure (kPa) | Volume (cm³) |
|---|
- Push the pump handle down (or press the Up arrow key) to increase the pressure; press Release (or the Down arrow key) to reduce it. Once you've collected your data, use the Graph Builder to help you plot it in step 4 below.
- Set the pressure to 100 kPa. Read the volume from the graduated tube and record both values.
- Pump the pressure up to 200 kPa. Before you read the volume — predict what you think it will be. Then record the actual value. Were you right?
- Record at least 6 pressure/volume pairs across the full range of the gauge.
- Plot a graph of Pressure against Volume. Draw a best fit curve.
- What pattern do you notice between pressure and volume?
- What does this pattern tell you about the relationship between pressure and volume?
