A very important part of a performance test on an A/C system is a pressure test. Pressure also is the key to the operation of the system. Which of the following statements is not true?

  1. Pressure on a substance, such as a liquid, changes its boiling point.

  • The greater the pressure on a liquid, the higher the boiling point.
  • If pressure is placed on a liquid, the liquid freezes at a higher-than-normal temperature.
  • The boiling point can be increased by increasing the pressure on the fluid. It can also be decreased by reducing the pressure or placing the fluid in a vacuum.
  • Blurred answer
