Question

Quizplus · Accepted Answer

As a bubble of air rises from the bottom of a lake, the pressure exerted on it by the surrounding water decreases. According to Boyle's Law, if the temperature remains constant, the volume of a gas is inversely proportional to the pressure exerted on it. Therefore, as the pressure decreases, the volume of the bubble increases, making choice B correct.
