Charles' Law states that the temperature of a gas is directly proportional to the volume. Compressing a gas increases the heat, and giving it more space allows the molecules slow in speed and cool down. The narrator proves this concept with a bicycle tire pump and a compressor. Both of these demonstrations can be done live in your classroom if you have the equipment.
