for every 10 m you descend below the surface of water, the

pressure on you will increase by an amount equal to
atmospheric pressure 101kpa. an air bubble in a lake has a
volume of 20 mm^3 at a depth of 40m. predict what volume it
will have just before reaches the surface?

0 --> 1 atm
10 --> 2 atm
20 --> 3 atm
30 --> 4 atm
40 --> 5 atm
20 * 5 = 100 mm^3
because V = nRT/P
