The radius of a soap bubble is r. the surface tension of soap solution is T, keeping temperature constant, the radius of the soap bubble is doubled the energy necessary for this will be-

There is a soap bubble of radius 2.4xx10^(-4)m in air cylinder which is originally at a pressure of 10^(5)(N)/(m^(2)) . The air in the cylinder is now compressed isothermally until the radius of the bubble is halved. (the surface tension of the soap film is 0.08Nm^(-1)) . The pressure of air in the cylinder is found to be 8.08xx10^(n)(N)/(m^(2)) . What is the value of n?

A soap bubble, having radius of 1mm, is blown from a detergent solution having a surface tension of 2.5 xx 10^(-2)N//m . The pressure inside the bubble equals at a point Z_(0) below the free surface of water in a container. Taking g= 10 m//s^(2) , density of water =10^(3)kg//m^(3) , the value of Z_(0) is

What is the excess pressure inside a bubble of soap solution of radius 5.00 mm , given that the surface of soap solution at the temperature (20^(@)C) is 2.50xx10^(-2)Nm^(-1) ?
