Concept:The equation shows pressure and volume are inversely related at constant temperature.Explanation:Boyle's law states that, for a fixed mass of gas at constant temperature, pressure is inversely proportional to volume.This means: P∝V1To remove the proportionality sign, a constant K is introduced.Therefore: P=VKThe given equation exactly matches this form.Hence, the law represented is Boyle's law.Answer:A. Boyle's law
