You are hiking to the top of Mt. Mitchell, NC (elevation 2 km). You start the hike at 0.5 km elevation where the air temperature is 20 C. There are cumulus clouds overhead with the cloud base at 1.5 km. When you reach the cloud base the air temperature will be [ Select ] v C. You continue hiking through the cloud until you reach the top of the mountain. At the top of the mountain the temperature will be [ Select] v C. (Assume that the dry adiabatic lapse rate is 10 C/km and the moist adiabatic lapse rate is 6 C/km)
