If your air conditioner is more than several years old, it may use the chlorofluorocarbon CCl2F2 as the heat transfer fluid. The normal boiling point of CCl2F2 is −29.8 °C, and the enthalpy of vaporization is 20.11 kJ/mol. The gas and the liquid have molar heat capacities of 117.2 J/mol ∙ K and 72.3 J/mol ∙ K, respectively. How much energy is evolved as heat when 18.2 g of CCl2F2 is cooled from +48.0 °C to –49.0 °C?
