Question

If the initial volume of the bubbles in a diver's blood is 15 mL and the initial pressure is 12.75 atm, what is the volume of the bubbles when the diver has surfaced to 1.00 atm pressure?

Answer 1

`V_2~=200*mL`

Explanation:

At constant temperature, `P_1V_1=P_2V_2`. Thus `V_2` `=` `(P_1V_1)/P_2`.

And thus, `(12.75*atm)/(1*atm)xx15*mL` `=` `??`

Of course, the temperature might have changed between depth and surface, but we have no way of interrogating this change. That diver is very deep `(>100*m)`. Sports divers would never go near that depth.
