A 12 litre gas bottle is initially charged with air to 232 BAR at 30 C. What will be the new pressure in the bottle once it has cooled to 8 C?

A diver breathes from the gas bottle above, is working at a depth of 40m, and at a temperature of 8 C.

If the diver exhales a bubble of air with a volume of 0.5 litres, what will the volume of the bubble be when it reaches the surface?

2. Relevant equations

not sure...

3. The attempt at a solution

I know for the first part that using the combined gas law

(P1/T1) x T2 = 215 BAR

P = pressure

T = temperature in kelvin

However i'm stuck on where to go with the next part.

Any pointers/hints in the right direction would be really appreciated. thanks
