B30 Define surface tension. Give a concise explana- tion of the origin of surface tension in terms of intermolecular forces. The pressure difference on the two sides of a spherical liquid-gas interface is 2;/R; what do "and Rrepresent? (You may use this expression fin (a) if you so wish, but you are advised to use it in parts (b) and (c).) (a) Derive an expression for the height of the liquid column in a vertical, uniform capillary tube. (Neglect any correction for the mass of the meniscus and assume that the angle of contact is zero.) Describe the experimental determination of the surface tension of water by the capillary rise method giving with reasons, a suitable value for the radius of the tube. (b) The two vertical arms of a manometer, containing water, have different internal radii of 10 'm and 2 x 10 'm respec- tively. Determine the difference in height
