9.1. An ice crystal in the form of a thin hexagonal plate grows by diffusion in an environment saturated with respect to water at a temperature of -4°C and a pressure of 80 kPa. Determine the time required for it to grow to a diameter of 1 mm, starting from a mass of 10-8 g. Take the capacity (capacitance, C) to be that of the circumscribing disk. Assume that the mass and the diameter of the plate are related by m = 1.9 X 10-2D³, with mass in g and D in cm. Neglect ventilation effects. If diameter and fall speed are related by u = KD; where K = 520 s-1, determine the distance the crystal falls during the growth to 1mm diameter.

The digital thermometers that we use in the lab today are similar to the ones that we use in our homes, but several years ago scientists used to use glass thermometers that contained a thin column of mercury to measure temperature. Why do you think we no longer use the mercury thermometers in the lab?
