Question

while scuba diving with some friends, deshawn notices that the air bubbles exhaled by his friends increase in size as they get closer to the surface of the water. why does this occur and which gas law explains it?

Explanation:

Step1: Understand pressure - volume relationship

As air bubbles rise, water pressure decreases.

Step2: Apply gas law

Boyle's law states $P_1V_1 = P_2V_2$ (at constant temperature and amount of gas). When pressure $P$ decreases (as bubbles rise), volume $V$ increases. So bubbles get larger.

Answer:

The air bubbles increase in size because the pressure exerted by the water decreases as they rise. Boyle's law explains this phenomenon.
