## Homework Statement

A bubble of air, 0.010m^3 in volume , is formed at the bottom of a lake which is 30m deep and where the temoperature is 8 degrees c. The bubble risees to the surface, where the water temp is 26 deg c and where the pressure is atmospheric pressure. What is the volume of the bubble just as it reaches the surface?

## Homework Equations

Im not sure how to attempt this problem but i used pv=nrt

r=8.31

## The Attempt at a Solution

i know that the n and the R have to stay constant, so i attempted by saying 100000(atmospheric pressure)*(.01)=(n)*(8.31)*(26-8)

but when i do that, i dont understand what i am solving for

will you please tell me if i am headed in the correct direction to solve this problem? thanks in advance.
