Explain the Relationship between Pressure and Volume for Gases.
Answer – As per Boyle’s law, the pressure of a gas is inversely proportional to its volume.
Explanation:
Boyle’s law states that at a constant temperature, increasing the pressure on a gas decreases its volume and vice versa.
Mathematically, this relationship can be expressed as PV = constant or V = constant / P, where P represents the pressure and V represents the volume of the gas. This inverse relationship is graphically represented by a hyperbola on a pressure-volume graph.

As seen in the graph above, it is evident that the relationship between these two variables is an inverse proportionality i.e. when one variable is increased, the other one decreases.
