If a saturated air mass descends down a slope its temperature increases at:

A higher rate than in dry air, as it gives up latent evaporation heat

A lower rate than in dry air, as condensation gives out heat

The same rate as if the air mass were dry

A lower rate than in dry air, as evaporation absorbs heat
