Charles's Law

The volume of a fixed amount of any gas at constant pressure varies linearly with temperature i.e.

V=constant ( t + 273.15)

where t is the gas temperature on Celsius scale. Charles's law concludes that the volume of any gas should extrapolate to zero at t = - 273.15 C. This law may be stated as following equation:

V=constant T

where T is the absolute temperature. Charles's law is a special case of the perfect gas equation.
