The Pressure-Volume relationship is given by Boyle’s law
The volume (V) of an ideal gas varies inversely with the applied pressure (P) when the temperature (T) and the number of moles (n) of the gas are constant.
Mathematically, Boyle’s law is represented as
V ∝ 1/P at constant T and n
or PV = Constant
- Boyle’s Law is used to predict the result of introducing a change in volume and pressure only to the initial state of a fixed quantity of gas.
