Quizplus · Accepted Answer

As a bubble of air rises from the bottom of a lake to the surface, the pressure exerted on it decreases. According to Boyle's Law, the volume of a gas is inversely proportional to the pressure exerted on it, assuming temperature remains constant. Therefore, as the pressure decreases, the volume of the bubble increases, making option C correct.
