## 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.
