Crushing Can
Crushing Can
Product code: B8A41798
Product Description
This can be used to show the forces exerted by atmospheric pressure.
A light walled tinplate can with an air-tight neck and screw cap. A small quantity of water in the can is boiled vigorously until steam occupies the space inside the can, at which point the top is screwed down tightly and the heat source removed. As the can cools down, atmospheric pressure is increasingly exerted until the can noisily collapses.
- Dimensions: (H)260mm x (D)75mm
- 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.
