CFCs are commonly used in which applications?

CFCs are commonly used in which applications?

• A. Refrigerators
• B. Aerosol sprays
• C. All of the above
• D. Air conditioners

Answer: (C)

CFCs were widely used because they are stable, non-toxic, and effective as cooling fluids and as propellants. They served as the refrigerant in many household refrigerators and in air conditioning systems, helping to transfer heat efficiently. They were also used as propellants in numerous aerosol sprays, enabling liquids to be expelled from cans. Because CFCs played a role in both refrigeration and aerosols, the option that includes all of these uses is the best answer. (Note: environmental concerns led to phasedown and replacements, but the historical uses include both refrigeration and aerosols.)
