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?

Answer 1

Sample Response: As the air bubbles rise to the surface, the pressure on them decreases. This decrease in pressure allows the air to expand and each bubble increases in size. Boyle’s law explains why this occurs.

Step-by-step explanation:

Answer 2

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 (
`P1*V1=P2*V2`).

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!
