Explanation

For an ideal gas, a graph of pressure (P) versus volume (V) at a constant temperature gives a hyperbolic curve, as described by Boyle's Law (PV = k).

This indicates an inverse relationship: as pressure increases, volume decreases, and vice versa.

However, if the graph is plotted between pressure (P) and the inverse of volume (1/V), it will be a straight line with a positive slope, passing through the origin
