Explanation

In 1787, the French scientist Jacques Charles discovered that the volume of a gas varies when we change its temperature, keeping the pressure constant.

Jacques Charles is known for Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature (in Kelvin) when pressure is held constant.

This relationship is fundamental in gas behavior studies.
