Question

1. an air conditioner uses a compressor to raise the temperature and pressure of ______. (1 point)

the inside air

the refrigerant

the outside air

Explanation:

In an air conditioner, the compressor's role is to increase the temperature and pressure of the refrigerant. The refrigerant undergoes a cycle where the compressor compresses it, raising its temp and pressure, then it releases heat outside, and later expands to cool. The inside air is cooled by the refrigerant, and the outside air is where heat is expelled, but the compressor acts on the refrigerant.

Answer:

B. the refrigerant (assuming the options are labeled as A: the inside air, B: the refrigerant, C: the outside air for clarity; the correct option is the one with "the refrigerant")
