The volume of an air bubble is doubled as it rises from the bottom of lake to its surface. The atmospheric pressure is 75cm of mercury.The ratio of density of mercury to that of lake water is 40The volume of an air bubble is doubled as it rises from the bottom of lake to its surface. The atmospheric pressure is 75cm of mercury. The ratio of density of mercury to that of lake water is 40/3. The depth of the lake in metre isa-10b-15c-20d-25;
10 meters.as volume is doubled,pressure at surface is half that at bottom of lake (assuming it cant xchange heat).also pressure at depth H is given by p(atm)+H*DENSITY OF WATER*g
