The law states that at constant pressure, the volume of a fixed mass of gas is directly proportional to its absolute temperature. It was found that for all gases (at any given pressure), the plots of volume vs. temperature is a straight line. If this line is extended to zero volume, then it intersects the temperature axis at -273⁰C.

In other words, the volume of any gas at 273 ⁰C is zero. This is because all gases get liquefied before reaching a temperature of 273⁰C.

Hence, it can be concluded that -273 ⁰C is the lowest possible temperature

From the given data,



According to Boyle's law,

                   


Substituting the values, we have,

   

The unit of pressure is given as= Nm^-2
The unit of volume is given as= m³
The unit of Temperature is given as= K²
Unit of mol is givne as = mol^-1.
Thus SI unit of given quantity is given as,
