While researching a topic, a student has taken the following notes:
• Freezers and other cooling technologies use chemical compounds called refrigerants to absorb heat and release cold air.
• When a refrigerant absorbs heat, it undergoes vaporization, changing from a liquid to a gas.
• When it cools, it undergoes condensation, changing from a gas to a liquid.
• The refrigerant fluoromethane is a hydrofluorocarbon (HFC).
• HFCs are composed of the elements hydrogen, fluorine, and carbon.
The student wants to describe the role of refrigerants in freezers. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Refrigerants can absorb heat and release cold air through vaporization and condensation.
A
The refrigerant fluoromethane, used in freezers, is made up of hydrogen, fluorine, and carbon.
B
Used in freezers, refrigerants such as fluoromethane can change from a gas to a liquid and back.
C
Freezers use refrigerants like fluoromethane to absorb heat and release cold air.
