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? hurrry plzz

Hello!

What Deshawn notices is that the volume of the bubbles increase as they get closer to the surface of the water.

This occurs because of the Boyle's Law. That Law states that when pressure decreases at constant temperature (like in water), the volume of a gas increases (). 

What is happening is that as the bubbles get closer to the surface of the water, the pressure on them decreases, causing their volume to increase, and that is seen by the increase in the size of the Bubbles that Deshawn noticed.

Have a nice day!
