What is Charles Law?
Charles’ Law, also called the law of volumes, states that at constant pressure the volume of a gas varies directly with the temperature. i.e. increase in the temperature of the gas results in an increase in the volume and conversely decrease in the temperature of the gas results in a decrease in the volume of the gas.
Suppose the initial temperature of the gas is T1 when its volume is V1 also, its volume at temperature T2 is V2. Now according to Charles’s Law.
V2/V1 = T2/T1
V1T2 = V2T1
This above equation establishes a proportional relation between the absolute temperature and the volume of the gas.
Defining Charles’ Law
Charles’s Law is defined as,
“The volume of a given mass of gas at constant pressure varies directly with its absolute temperature.”
Charles Law
Charles Law is one of the fundamental laws used for the study of gases. Charles Law states that the volume of an ideal gas is directly proportional to the temperature (at absolute scale) at constant pressure. Famous French physicist Jacques Charles formulated this law in the year 1780.
