Chlorofluorocarbons are commonly used as Freon in refrigerators and air conditioners. Cooling the average dorm room from 35°C to 22°C requires the air conditioner to convert ~2700 g of C2Cl3F3 from a liquid at 24.7 °C to a gas at 87.0 °C. How much energy in kJ is absorbed by the chlorofluorocarbon when cooling this room? The chlorofluorocarbon C2Cl3F3 has a normal boiling point of 47.6 °C. The specific heat of the liquid is 0.91 J/g⋅K. The specific heat of the gas is 0.67 J/g⋅K. The heat of vaporization is 27.49 kJ/mol.
