An inverted bell lying at the bottom of a lake `47.6 m` deep has `50 cm^3` of air trapped in it. The bell is brought to the surface of the lake. The volume of the trapped air will be (atmospheric pressure `= 70 cm` of `Hg` and density of `Hg = 13.6 g//cm^3`).

An inverted vessel (ball) lying at the bottom of a lake, 47.6 m deep, has 50 c.c. of air trapped in it. The bell is brought to the surface of the lake. The volume of the trapped air will now be (Atmospheric pressure is 70 cm of Hg, density of HG - 13.6 g cm^(-3) )

An inverted vessel (bell) lying at the bottom of a lake, 47.6 m deep, has 50 cc of air trapped in it. The bell is brought to the surface of the lake. What will be the volume of the air trapped in it now, if temperature remains constant? (Atmospheric pressure = 70 cm of Hg and density of Hg = 13.6 g/cc) express it as ( x xx 100) .

At what depth below the surface of a lake will the total pressure be twice the atmospheric pressure? (Atmospheric pressure = 76 cm Hg and the density of mercury = 13.6 g*cm^(-3) )

Calculate the pressure at the bottom of a fresh water lake of depth 10 m. The atmospheric pressure = 76 cm of mercury and the density of mercury = 13.6g*cm^(-3) .

As an air bubble rises from the bottom of a lake to the surface, its volume is doubled. Find the depth of the lake. Take atmospheric pressure = 76 cm of Hg.

As an air bubble rises from the bottom of a lake to the surface, its volume is doubled. Find the depth of the lake. Take atmospheric pressure = 76 cm of Hg.

As an air bubble rises from the bottom of a lake to the surface, its volume is doubled. Find the depth of the lake. Take atmospheric pressure = 76 cm of Hg.

Radius of an air bubble at the bottom of the lake is r and it becomes 2 r when the air bubbles rises to the top surface of the lake. If P cm of water be the atmospheric pressure, then the depth of the lake is

An air bubble starts rising from the bottom of a lake. Its diameter is 3.6 mm at the bottom and 4mm at the surface. The depth of the lake is 250 cm and the temperature at the surface is 40^@C . The atmospheric pressure is 76 cm of Hg and g=980 cm.s^-2 . What is the pressure at the bottom of the lake?
