1. The problem statement, all variables and given/known data A bubble rises from the bottom of a lake of depth 90 m, where the temperature is 4°C. The water temperature at the surface is 19°C. If the bubble's initial diameter is 1.00 mm, what is its diameter when it reaches the surface? (Ignore the surface tension of water. Assume the bubble warms as it rises to the same temperature as the water and retains a spherical shape. Assume Patm = 1.0 atm.) 2. Relevant equations P1V1/T2=P2V2/V2 Vsphere = 4/3 pi r^3 P=pgd 3. The attempt at a solution (1000*9.8*90/1000)*4/3*pi*.5^3/4=101.3*4/3*r^3/19 I get 3.458, which isn't right. Am I missing something?
