Question

question 9
why is the moist adiabatic lapse rate (malr) different than the dry adiabatic lapse rate (dalr)?
a the malr and dalr are equal to one another
b condensation releases latent heat, offsetting the effects of adiabatic cooling
c condensation releases water vapor, which requires more energy than dry air

Explanation:

The dry adiabatic lapse rate (DALR) applies to dry air. When air is moist and rises, condensation occurs. Condensation releases latent heat. This released heat offsets some of the cooling that would occur due to adiabatic expansion. So, the moist adiabatic lapse rate (MALR) is less steep than the DALR.

Answer:

B. Condensation releases latent heat, offsetting the effects of adiabatic cooling
