Answer to Question 1

Answer: The dry adiabatic lapse rate is valid for unsaturated parcels and the saturated adiabatic lapse rate is valid for saturated parcels. Once saturation occurs, the latent heat of condensation adds heat to the parcel.

Answer to Question 2

Answer: Potential instability arises when a layer of dry air overlays a layer of warm and moist air. Lifting of these layers can increase the lapse rate, thereby creating an unstable situation out of a stable one.
