Liquid ammonia, NH₃(ℓ), was once used in home refrigerators as the heat transfer fluid. The specific heat capacity of the liquid is 4.7 J/g ∙ K and that of the vapor is 2.2 J/g ∙ K. The enthalpy of vaporization is 23.33 kJ/mol at the boiling point. If you heat 12 kg of liquid ammonia from −50.0°C to its boiling point of −33.3°C, allow it to evaporate, and then continue warming to 0.0°C, how much energy must you supply?
