1. Which of the following terms describes thermal energy transfer through direct contact between solid objects?
Conduction
Convection
Radiation
The purpose of a Thermostatic expansion valve is to:
control the flow of refrigerant into the evaporator
increase the pressure of the refrigerant
decrease the temperature of the refrigerant
compress the refrigerant
Name 3 types of AC compressors.
Swash plate, Rotary, and Scroll
Centrifugal, Axial, and Diagonal
Piston, Screw, and Vane

A brief description of the operation of a compressor is:
It increases the pressure of a gas by reducing its volume.
It decreases the pressure of a gas by increasing its volume.
It maintains the pressure of a gas without changing its volume.
It changes the temperature of a gas without affecting its pressure.
