Hey, my friend and I have worked on this problem for about 2 hours straight (from our online HW) and can't get the answer right. The help offices and the professor are closed/gone for the weekend. Can anyone please help?!
At 80.0m below the surface of the sea (density = 1.025g/cm3) where the temperature is 5.0°C, a diver exhales an air bubble having a volume of 1.00cm3.
If the surface temperature of the sea is 20.0°C, what is the volume of the bubble just before it breaks the surface? [in]cm3
We've tried using PV=nRT and setting PiVi/Ti=PfVf/Tf and solving for Vf (using pressure formula Pressure at sea level+(density*g*depth) to find the pressure at 80.0m and then using atmospheric pressure for Pf, but to no avail.
Perhaps someone can tell us what to do and/or give an answer to check against all that we got?
Thanks.
