Question

Quizplus · Accepted Answer

As the rising air reaches the dew point, it undergoes condensation, which releases latent heat and warms up the air. At the same time, the air is also expanding due to decreasing atmospheric pressure, which causes it to cool down. Therefore, the correct statement is that the air is simultaneously being cooled by expansion and heated by condensation.
