Question

13 The equations of the sublimation and the vaporization curves of a particular material are given by (sublimation). (vaporization) In P 0.04-6/T In P 0.03 - 4/T T + dT = const. T const. Figure 8.4 P. o diagrarn for an infinitesimal Carn ot cycle. where P is in atmospheres (a) Find the temperature of the triple point. (b) Show that the spe cific latent heats of vaporization and sublimation are 4R and 6R, respectively. (You may assume that the specific volume in the vapor phase is much larger than the specific volume in the liquid and solid phases) (c) Find the la tent heat of fusion.
