The sublimation of zinc (mass per mole 0.0654 kg/mol)
Chapter 15, Problem 15.40(choose chapter or problem)
The sublimation of zinc (mass per mole 0.0654 kg/mol) takes place at a temperature of 6.00 102 K, and the latent heat of sublimation is 1.99 106 J/kg. The pressure remains constant during the sublimation. Assume that the zinc vapor can be treated as a monatomic ideal gas and that the volume of solid zinc is negligible compared to the corresponding vapor. What is the change in the internal energy of the zinc when 1.50 kg of zinc sublimates?
