Calculate the work done when a system raises a colume of water of radius `5.0mm` through `10cm`.

Calculate the work done when done when 1.0 mol of water at 373K vaporises against an atmosheric pressure of 1.0atm . Assume ideal gas behaviour.

Calculate the work done when done when 1.0 mol of water at 373K vaporises against an atmosheric pressure of 1.0atm . Assume ideal gas behaviour.

Calculate the work done when a water drop of diameter 2mm is split into 10^(9) identical water droplets. Surface tension of water is 7.4xx10^(-2)Nm^(-1) .

Calculate the amount of work done, when a force of 25 N displaces a body through 10 m, in its own direction.

Calculate the work done when a force of 60 N displaces a body through 10 m in the direction of the force.

Calculate the loss of energy when 27 drops of water each of radius 0.6mm coalesce to form a single drop.

Surface tension changes with temperature. Calculate the work done in breaking water drop of radius 1 mm to 1000 droplets. Surface tension of water = 72 x 10^(-3) N/m .

Calculate the work done to increase the radius of a soap bubble from 4 cm to 5cm. sigma = 25 xx 10^(-3) Nm^(-1) .
