Why does the adiabatic rate of cooling change when condensation begins? Why does the adiabatic rate of cooling change when condensation begins? The rate changes because the air parcel is closer to the sun. The rate changes because the sensible heat that was absorbed by the water vapor when it evaporated is released as sensible heat. The latent heat quickens the rate of cooling during the air parcel's ascent. The rate changes because the latent heat that was absorbed by the water vapor when it evaporated is released as sensible heat. Sensible heat slows the rate of cooling during the air parcel's ascent. The rate changes because the sensible heat that was absorbed by the water vapor when it evaporated is released as sensible heat. The latent heat slows the rate of cooling during ascension.
