Boyes's law states that at constant temperature(T) for a given mass of ideal gas, the volume(V) of the gas is inversely proportional to its pressure(P).
That is PV=K where K is a constant
Graphs of Boyle’s law can be plotted at different temperatures.
The graph of Boyle’s law is known as a pressure-volume graph or PV curve.
The pressure and volume graph at constant temperature is known as an isotherm
As the Pressure increases with decreasing in volume, and vice versa.
Other parameters such as temperature and amount of gas are constant in the graph.
The equation of the curve is PV=K, which is the equation of Boyle’s law
