Charle's Law

In 1787, French scientist Charles (1746-1823) found that the temperature and volume of a gas were proportional. Whenever the temperature of the gas increases by 1 ° C, it increases by 1/273 of its volume at 0 ° C.

When the pressure is constant, increasing the temperature of the gas will speed up the molecular motion and increase the volume of the gas. Conversely, lowering the temperature of the gas slows the molecular motion and reduces the volume of the gas. At this time, the volume change of the gas does not depend on the type of gas.
