Interpretation:
Two uses of CFCs should be listed.
Concept introduction:
CFCs stand for chlorofluorocarbons. These are non-toxic and nonflammable chemicals. These are halogenated saturated hydrocarbons which contain atoms of carbon, chlorine, and fluorine and produced as volatile derivative of

Answer to Problem 1RQ
Solution:
Chlorofluorocarbons are used as a cooling fluid in freezers and refrigerators. They are also used as a blowing agent for foams and packing material.
Explanation of Solution
Chlorofluorocarbons have wide applications due to its nontoxic and inflammable nature. They are used in refrigerators and freezers in the form of cooling fluids. They are also used as a blowing agent for packing materials and foams.
Chlorofluorocarbons causes depletion of ozone layer. In high atmosphere, the bonds between carbon and chlorine break to produce chlorine free radicals which destroy ozone.
Chlorofluorocarbons are used as a cooling fluid in freezers and refrigerators. They are also used as a blowing agent for foams and packing material.
