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 CCl₂ F₂ is -29.8 °C, and the enthalpy of vaporization is 20.11 kJ/mol. The gas and the liquid have molar heat capacitie 117.2 J/mol K and 72.3 3/mol K, respectively. How much energy is evolved as heat when 20.8 g of CCl₂ F₂ is cooled from +40.0 °C 41.0 °C? Energy evolved
