Question

A diver observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm to the surface (where the pressure is 1.00 atm). The temperature at the bottom is 5.00 C and the temperature at the surface is 25.0 C. What is the ratio of the volume of the bubble as it reaches the surface to its volume at the bottom? Would it be safe for the diver to hold his breath while ascending from the bottom of the lake to the surface? Why or why not?

Explanation / Answer

At bottom P1V1 = nRT1 ( T1 = 5.00C = 278 K) ==> 3.5*V1 = nR*278 Similarly at surface 1*V2 = nR*298 ==> V2/V1 = 298*3.5/278 = 3.75 It is not safe for the diver to hold his breath while ascending from the bottom of the lake to the surface because the volume of air hold inside increases to 3.75 times as that at the bottom which is very dangerous.
