ESCO Air Conditioning Practice Exam

Which of the following is not a thermodynamic property of refrigerants

1. Boiling Point

2. Flammability

3. Heat Capacity

4. Vapor Pressure

The correct answer is: Boiling Point

The boiling point of a refrigerant is a physical property rather than a thermodynamic property. Thermodynamic properties are characteristics that can be measured and used to analyze thermodynamic processes, such as pressure, temperature, enthalpy, entropy, specific heat, and heat capacity. In contrast, the boiling point is a specific temperature at which a substance changes from a liquid to a gas or vapor at a given pressure. Therefore, among the options provided, the boiling point is not a thermodynamic property of refrigerants.
