Answer to Question 2
Adiabatic temperature changes occur when air expands or contracts and consequently undergoes a pressure change. Adiabatic temperature changes require that no energy exchange takes place with the surrounding environment. Air that is not saturated will cool at 10C/km, known as the dry adiabatic lapse rate, as it rises and expands in the atmosphere. Once the air becomes saturated, however, water vapor in the parcel will begin to condense. This condensation releases latent heat energy into the parcel that becomes sensible heat, partially counteracting the adiabatic cooling that occurs as the parcel continues to expand. For this reason, the wet adiabatic lapse rate is lower than the dry adiabatic lapse rate (about 5C at its lowest).
