This apparatus vividly demonstrates the rise in temperature that occurs when a fixed mass of air in a transparent cylinder is compressed by a hand operated piston. A piece of tinder, which is provided, ignites in the transparent cylinder: much as a diesel engine obtains ignition. The cylinder and piston can also be used to demonstrate the effect of decompression, being the immediate lowering of temperature and the consequent condensation of water vapour inside the cylinder - the cloud formed can easily be seen.
Cylinder Dimensions: (L) 198.00 mm (OD) 15.00 mm (ID) 9.00 mm
