A glass capillary of diameter 0.13 cm is dipped into a liquid. Calculate the level of the liquid in the capillary in each case. (a) water (contact angle 13) at 293 K. (The density of water at this temperature is 0.998 g.cm-3.) cm (b) mercury (contact angle 165) at 298 K. (The density of mercury at this temperature is 13.5 g.cm -3.) cm What is the diffusion coefficient of a membrane-bound protein of molar mass 79,300 daltons at 37C if the viscosity of the membrane is 1 poise (0.10 N.s.m-2)? Assume that this protein is an unhydrated, rigid sphere that has a density of 1.4 g.cm-3. 4.0 m2.5-1 What is the average distance traveled by this protein in 2.3 s? 4.0
