Produced by the National STEM Centre and the Institute of Physics, this video demonstrates how compressing a gas increases its temperature. A small piece of cotton wool is placed into the bottom of a narrow plastic tube. When the air is rapidly compressed by a piston, the air temperature increases and the cotton ignites. The 'fire piston' can be used to illustrates the transfer of energy, kinetic theory and Charles' law.
