1. The problem statement, all variables and given/known data To measure the depth of a lake, an empty bottle (V=1dm^3) is lowered to the bottom of the freshwater lake. There is a weight attached to the bottom of the bottle to keep it upright. When the bottle is recovered it is filled with 0,58dm^3 of water. Determine the depth of the lake. Assume constant temperature and standard atmospheric conditions. 2. Relevant equations Boyle's law says pV=constant pressure at height h is p(atm)+density of water*g*h V2=0,42dm3 3. The attempt at a solution p2=(p1V1)/V2=p(atm)+density of water*g*h I solve for h and i got h=14,3m after substituting numbers in. Am I right?
