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.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
