If your air conditioner is more than several years old, it may use the chlorofluorocarbon CCl2 F2 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 capacities of 117.2 J/mol K and 72.3 J/mol K, respectively. How much energy is evolved as heat when 16.6 g of CCl₂ F2 is cooled from +38.0 °C to -48.0 °C? Energy evolved =

Question
If your air conditioner is more than several years old, it may use the chlorofluorocarbon CC12F2 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 capacities of 117.2 J/mol K and 72.3 J/mol · K, respectively. How much energy is evolved as heat when 16.6 g of CC12F2 is cooled from +38.0 °C to -48.0 °C? Energy evolved = J
