HAC-101 Week 10 Review Flashcard

Front

The Clean Air Act (CAA)___________.

Back

All of the above.

Answer explanation

The Clean Air Act (CAA) encompasses all aspects of air-conditioning work, including licensing, refrigerant safety, and shop standards, making 'All of the above' the correct choice.

Front

The 609 license never expires.

Back

True

Answer explanation

The 609 license, which pertains to consumer rights under the Fair Credit Reporting Act, does not have an expiration date, making the statement true.

Front

The 609 License ensures that the technician knows how to repair the automotive air-conditioning systems.

Back

False

Answer explanation

The 609 License pertains to refrigerant handling, not specifically to repairing automotive air-conditioning systems. Therefore, the statement is false.

Front

Section 609 of_____ the federal law regulates air emissions from stationary and mobile sources contains all of the motor vehicle air-conditioning (MVAC) requirements and laws.

Back

The Clean Air Act (CAA)

Answer explanation

The Clean Air Act (CAA) is the federal law that regulates air emissions from both stationary and mobile sources, including the requirements for motor vehicle air-conditioning (MVAC). Therefore, it is the correct answer.

Front

The_____ of the refrigerant system system is designed to allow easy transformation of the refrigerant from a liquid to a gas.

Back

Low Side

Answer explanation

The Low Side of the refrigerant system is where the refrigerant transitions from a liquid to a gas. This side operates at lower pressure, facilitating the evaporation process essential for cooling.

Front

The amount of heat required to raise the temperature of 1 pound of water at 32*F (0*C) and at atmospheric pressure by 1*F would be:_____

Back

1 BTU

Answer explanation

The correct answer is 1 BTU, which is defined as the amount of heat required to raise the temperature of 1 pound of water by 1°F at atmospheric pressure. Other options do not represent this specific heat measurement.

Front

When the pressure of a gas is raised, its temperature:

Back

goes up

Answer explanation

According to Gay-Lussac's law, when the pressure of a gas increases at constant volume, its temperature also increases. Therefore, when the pressure of a gas is raised, its temperature goes up.

Front

Radiation describes the amount of heat it takes to move temperature up or down in degrees.

Back

False

Answer explanation

The statement is false because radiation refers to the emission of energy as electromagnetic waves, not the heat required to change temperature. The correct term for that concept is 'heat capacity'.

Front

The A/C compressor clutch is engaged and is disengaged by using:_____

Back

Electromagnetism

Answer explanation

The A/C compressor clutch is engaged and disengaged using electromagnetism. When electrical current flows through the coil, it creates a magnetic field that pulls the clutch in, allowing the compressor to operate.

Front

The air-conditioning hose connections are secure to the hose using special unions known as _____ that must be carefully assembled to avoid leaks.

Back

Crimps

Answer explanation

The correct term for the special unions used to secure air-conditioning hose connections is 'crimps'. Crimps are designed to tightly fasten hoses and prevent leaks, making them essential for proper assembly.
