Question

What happens when a refrigerant is compressed and condensed?

A. It condenses back into a liquid, giving up heat to the outside air.
B. It vaporizes, so it can escape to the outside air.
C. The pressure on it decreases, so it can exchange heat with the outside air.
D. It remains a gas but takes heat from the outside air.

Answer 1

When a refrigerant is compressed and condensed, it undergoes a specific process in a refrigeration system. The correct answer to the question is:

A. It condenses back into a liquid, giving up heat to the outside air.

Here's a step-by-step explanation:

1. Compression: When a refrigerant is compressed, it is typically in a gaseous state. The compressor in the refrigeration system increases the pressure of the refrigerant, causing it to become highly compressed.

2. Condensation: As the compressed refrigerant moves through the condenser, it releases heat to the outside air. This heat exchange causes the refrigerant to cool down and condense from a gas into a liquid state.

3. Liquid State: In its condensed liquid state, the refrigerant is now at a high pressure and temperature. It is ready to be further processed in the refrigeration system to absorb heat from the desired area.

In summary, when a refrigerant is compressed and condensed, it transforms from a gaseous state to a liquid state, releasing heat to the outside air. This condensed liquid refrigerant can then continue its journey through the system to absorb heat from the desired area, contributing to the cooling process.

Answer 2

Step-by-step explanation:

the answer is: A
A. It condenses back into a liquid, giving up heat to the outside air.

When a refrigerant is compressed, it becomes a high-pressure gas, which is then condensed by removing heat from it. As a result, the refrigerant condenses back into a liquid and releases heat to the outside air. This liquid refrigerant then passes through the expansion valve and enters the evaporator, where it absorbs heat from the surrounding environment, such as the air in a room. The absorbed heat causes the liquid refrigerant to evaporate back into a gas, which is then compressed again, and the cycle repeats. Therefore, option A is the correct answer.
