Descriptions

This apparatus provides an excellent method of demonstrating Boyles Law. The unit is mounted on a sturdy Perspex board. The gauge and syringe are connected by a high pressure hose.

This is a good way to visualize the basic relationship between pressure, volume and temperature of gases. To show Boyle's Law, connect the calibrated syringe to the pressure gauge. The entire class can view the corresponding pressure change as the volume of gas in the syringe is varied. Students can graph the results.

Includes instructions.

Learning Outcomes:

Key Stage 3 Chemistry - The particulate nature of Matter: The properties of the different states of matter (solid, liquid and gas) in terms of the particle model, including gas pressure.

Key Stage 4 Physics - The Structure of Matter: Links between pressure and temperature of a gas at constant volume, related to the motion of its particles (qualitative).  Explain why the work done in the compression or expansion of gases is the product of the pressure and the change in volume.
