Compounds like CCl2F2 are known as chlorofluorocarbons, or CFCs. These compounds were once widely used as refrigerants but are now being replaced by compounds that are believed to be less harmful to the environment. The heat of vapoization of CCl2F2 is 289J/g.
What mass of this substance must evaporate in order to freeze 100g of water initially at 18 degrees C?
Heat of fusion of water is 334 J/g and the specific heat of water is 4.18 J/g-K
