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.
If the volume of a gas is halved while the temperature remains constant, what happens to its temperature according to Charles’s Law?
