Charle’s law is represented mathematically as

Charle’s law can express mathematically as given below.

${\mathrm{V}}_{\mathrm{t}}={\mathrm{V}}_0\left[1+\frac{\mathrm{t}}{273}\right]$

It means that a fixed mass of a gas at constant pressure, volume of a gas increases on increasing temperature and decreases on decreasing temperature by the value of   $\frac{1}{273.15}$ of its original volume of gas at °C  for every 1°C  rise in temperature
