ESCO Air Conditioning Practice Exam

The movement of heat by direct contact is called

1. Conduction

2. Convection

3. Radiation

4. Superheat

The correct answer is: Conduction

Conduction is the correct answer because it refers to the transfer of heat through direct contact between two objects at different temperatures. In this process, heat energy flows from the warmer object to the cooler one until thermal equilibrium is reached. Convection involves the transfer of heat through the movement of fluids such as air or water. Radiation is the transfer of heat in the form of electromagnetic waves. Superheat, on the other hand, refers to the temperature of a vapor or gas above its boiling point.
