Rising parcels of saturated (cloudy) air do not cool as rapidly as rising air parcels of unsaturated (clear) air because:
a. rising air parcels of saturated air do work in expanding.
b. expansional cooling of saturated air is partially compensated for by release of latent heat that accompanies cloud formation.
c. saturated air parcels are always warmer than their surroundings.
d. all of the above are correct.
e. none of the above are correct.
