Answer» An air bubble starts rising from the bottom of a lake. Its diameter is $3.6 mm$ at the bottom and $4 mm$ at the surface. The depth of the lake is $250 cm$ and the temperature at the surface is $40^{\circ} C$ . What is the approximate temperature at the bottom of the lake in $^{\circ} C$ .? Given atmospheric pressure $= 76 cm of Hg$
