A. A lifted parcel of air will be colder (heavier) that the air surrounding it. Because of this fact, the lifted parcel will tend to sink back to its original position. b. The rate of adiabatic cooling or warming that occurs in a parcel of air that is unsaturated. c. The level at which a lifted parcel of air becomes saturated, marking the base of a cumuliform cloud d. If a parcel of air expands and cools, or compresses and warms, and there is no interchange of heat with its outside surroundings. e. If rising air cools to its dew-point temperature, condensation results forming a cloud. Because heat added during condensation offsets some of the cooling due to expansion, the air cools at a lower rate. f. The level at which a lifted parcel of air in a conditionally unstable atmosphere becomes warmer (lighter) than its environment and continues to rise freely g. A lifted parcel of air will be warmer (lighter) than the air surrounding it, and thus will continue to rise upward, away from its original position.
