The surface tension of soap solution is 0.03 Nm^(-1) . The work done in blowing to form a soap bubble of surface area 40 cm^2 , (in J), is
What is surface tension of liquids? Explain the affect of temperature on the surface tension of liquids.
Regarding the surface tension property of liquids, the correct statements is/are a) surface tension decreases with increase of temperature b) at 20^@ C the surface tension of ethanol is greater than that of water c) the dimensions of surface tension is SI units is Nm^(-1) d) in the fine polishing of the glass, the edges become smooth due to surface tension
A liquid drop of density rho is floating half immersed in a liquid of surface tension S and density rho/2 . If the surface tension S of the liquid is numerically equal to 10 times of acceleration due to gravity, then the diameter of the drop is :
