This law was given by J.Charles in 1787.
The volume of a given mass of a gas is directly proportional to the absolute temperature or Kelvin.
In other words, if the temperature of a gas is doubled at constant pressure, its volume also doubles, and if the temperature is halved, its volume is reduced to half. Mathematically, this law can be expressed as:
V/T = K
where V is the volume of the gas, T is its absolute temperature, and k is a constant of proportionality.
The equation can be rearranged as:
V1/T1 = V2/T2
where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.This equation is used to determine the volume of a gas at different temperatures or to calculate the temperature of a gas at different volumes. It is an essential tool in the study of thermodynamics and has many practical applications, including the design and operation of engines and refrigeration systems.
