ocr: CHAPTER 11 Solutions to Exercises Intermolecular Forces, Liquids and Solids 11.22 (a) CHBra has a higher molecular weight, is more polarizable and has stronger dispersion forces, so the surface tension is greater (see Exercise 11.16(b)). (b) As temperature increases, the viscosity of the oil decreases because the average kinetic energies of the molecules increase (Exercise 11.20). (c) Adhesive forces between polar water and nonpolar car wax are weak, sO the large surface tension of water draws the liquid into the shape with the smallest surface area, a sphere.
