### What is Meant by Charles Law?

In Chemistry, Charles law states that the volume of gas for a fixed mass is directly proportional to the temperature. It is also known as the law of volumes. This law defines how the gas expands when the temperature is increased. Charles law is the special case of the ideal gas law.

The formula to calculate the volume of the gas under two different conditions are as follows:

V2/V1 = T2/T1

Where

T1 and T2 are the initial and final temperature

V1 and V2 are the initial and final volume
