The chlorofluorocarbon ccl2f2 was once used in air, Ask an Expert

Academics

The chlorofluorocarbon CCl2F2 was once used in air conditioners as the heat transfer fluid. Its normal boiling point isâ€¨-30 °C, and its enthalpy of vaporization is 165 J g-1. The gas and the liquid have specific heat capacities of 0.61 J g-1â€¨ °C-1 and 0.97 J g-1 °C-1, respectively. How much heat is evolved when 10.0 g CCl2F2 is cooled from 40 °C to -40 °C?
