1. The problem statement, all variables and given/known data A bubble rises from the bottom of a lake of depth 80.0 m, where the temperature is 4oC. The water temperature at the surface is 18oC. Assume the bubble to be in spherical shape and has an initial diameter of 1.00 mm. Assume that the pressure at the surface of the lake is 1.0 atm. Calculate a) the pressure at the bottom b) the number of moles and molecules in the bubble and c) the diameter of the bubble at the surface. 2. Relevant equations PV=nRT P(bottom) = P(atm) + d(ro)*g*h 3. The attempt at a solution I have solved part a and c but I cannot answer part b. The answer to part a is 885300 Pascals and the answer to part c is 2.09 mm but no mater what I try I cannot get the correct answer to past b.
