Charles's law states that

This holds true for an ideal gas.
History
Charles's law was apparently discovered by Jacques Alexandre César Charles in 1787, as mentioned by Joseph Louis Gay-Lussac (Ref. 1):
"Although I had recognized on many occasions that the gases oxygen, nitrogen, hydrogen, carbonic acid, and atmospheric air all expand identically from 0° to 80°, citizen Charles had noticed the same property in these gases 15 years ago; however, since he never published his results, it is only by great luck that I knew it."
