Charles's Law

Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated.
French physicist Jacques Charles (1746 - 1823) studied the effect of temperature on the volume of a gas at constant pressure. Charles's Law states that the volume of a given mass of gas varies directly with the absolute temperature of the gas when pressure is kept constant. The absolute temperature is temperature measured with the Kelvin scale. The Kelvin scale must be used because zero on the Kelvin scale corresponds to a complete stoppage of molecular motion.

Charles's Law Formula

Charles's Law can also be used to compare changing conditions for a gas. Now we use V1 and T1to stand for the initial volume and temperature of a gas, while V2 and T2stand for the final volume and temperature. The mathematical relationship of Charles's Law becomes:
V1/T1 = V2/T2
