When an air bubble rises from the bottom of a lake to the surface, its radius, is doubled. Atmospheric pressure is equal' to the pressure of a water column of height it. Depth of the lake is-

When an air bubble rises from the bottom of a lake to the upper surface , its diameter increases from 1mm to 2mm. IF the atmospheric pressure is 76 cmHg,calculate the depth of the lake. Density of mercury is 13.6g.cm^-3 .

A bubble of gas released at the bottom of a lake increases to eight times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water, 10 m height, the depth of the lake is correct 80 M 90 M 40 m 10 m 70 m

When an air bubble rises from the bottom of a sea its volume increases to 4 times its initial value. IF the atmospheric pressure is 76 cmHg and the temperatures at the bottom and the surface of the sea are the same. Then what will be the depth of the sea? Density of mercury= 13.6 g.cm^-3 .

An air bubble of diameter 1 mm is formed at the bottom of a lake and when it rises to the surface of the water, its diameter becomes 2 mm. If the atmospheric pressure is 760 cm of mercury, then find the depth of the lake. (Density of mercury = 13.6g*cm^(-3) )

A spherical air bubbles is rising from the depth of a lake when pressure is P atm and temperature is T K what is the percentage increase in its radius when it comes to the surface of a lake. (Assume : temperature and pressure at the surface to be respectively 2T K and P/4 )
