An air bubble floats up on the surface of water from the bottom of a river of depth 34 m. At the bottom the temperature of water is `7^@C` and the volume of the bubble is `14 cm^3` Temperature on the surface of the water is `27^@C` and the pressure is 75 cmHg. IF the density of mercury is `13.6 g.cm^-3` them what will be the volume of the bubble on the surface of water?
