From Wikipedia, the free encyclopedia. A modern statement of Charles's law is:. The statement of Charles's law is as follows: Gas laws. This law describes how a gas expands as the temperature increases; conversely, a decrease in temperature will lead to a decrease in volume. The kinetic theory equivalent of the ideal gas law relates PV to the average kinetic energy:. Gas laws History of thermodynamics.
As the gas cools, the volume decreases to 3.
Charles did the original work, which was verified by Gay-Lussac. Step 2: The initial state of the gas has a volume qual to 4.
When the temperature of a sample of gas in a rigid container is increased, the pressure of the gas increases as well.
