An Irish natural philosopher, Robert Boyle, conducted experiments to verify properties of gases discovered by other scientists. Boyle's law mathematically describes the inversely proportional relationship between the absolute pressure and volume of a gas. This means that if the volume of a container of gas is decreased, the amount of pressure in that container will increase proportionally. This relationship is a (2 points)
