Answer to Question 1

Stability is the tendency of an air parcel to either remain in place or to change vertical position by ascending or descending. An air parcel is stable if it resists displacement or returns to its starting place after disturbance. The stability of an air parcel depends on the temperature inside the parcel and the temperature of the surrounding air. As air ascends, it is cooled by expansion and as it descends, it is heated by compression. These cooling and heating mechanisms are adiabatic, that is occurring without a loss of gain of heat (heat exchange between the surrounding environment and the ascending or descending parcel).
