Other common examples of Charles' law involve helium balloons, tire pressure and dented table tennis balls. Helium balloons shrink when brought out into cold temperatures but can return to their original shape when brought back into warmer temperatures. Car manuals state that tire pressure should be measured in cold weather, since tire pressure is higher in warm weather. Dented table tennis balls can be restored to their original shapes by placing them in a sauce pan full of water and gently increasing the heat of the water; as it heats, the air in the ball expands and pushes out the dent.

Charles' law states that increasing the temperature of a gas increases its volume. The law was introduced in the early 1800s in France by Jacques Charles and Joseph-Louis Gay-Lussac. These two scientists used the popularity of hot air balloons to test how the volume of the gas was affected by the temperature of the gas.
