A compound is characterized by the following constants:
Heat of fusion = 75 cal/g
Heat of vaporization = 20 cal/g
The heat of deposition for the same compound is
heat fusion is 75 cal/g (solid to liquid)
heat vaporization is 20 cal/g (liq to vapor)
heat sublimation = 95 cal/g (75+20)(solid to vapor)
heat deposition, the reverse of sublimation, is -95 cal/g.
