What will be the expression for the differential form of Boyle’s law? 

Explanation

To derive the differential form of Boyle's Law, we start with the basic understanding of Boyle's Law itself. Boyle's Law states that the pressure (P) of a gas is inversely proportional to its volume (V) when the temperature is held constant. Mathematically, this can be expressed as:

\[ P \propto \frac{1}{V} \]

This can also be written as:

\[ PV = k \]
