Question

As an air bubble rises from the bottom of a large
water storage tank to free surface of water, the radius
of the air bubble increases from 6 mm to 10 mm. The
temperature of the water at the surface is 42°C and
its bottom is 27°C. Find the depth of the water tank.
(Take density of water = 1 g cm, g = 10 ms^-2
1 atmospheric pressure = 760 mm of Hg: density of
mercury = 13.6 g cm)​
