Charles' Law

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Charles' law is one derivation of the Ideal Gas Law.  Charles' law states that at equal pressures, the pressures and temperatures are inversely related. 

At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in Kelvin) increases or decreases.

Charles' law assumes that there is no pressure change in the process.

formula

\(\frac{V_1}{T_1} = \frac{V_2}{T_2}\)

Where:

\(V_1\) = volume

\(V_2\) = volume

\(T_1\) = absolute temperature

\(T_2\) = absolute temperature
