A parcel of air at 5 km and an initial temperature of 10°C altitude descends to 3 km altitude at the unsaturated adiabatic lapse rate.What is the temperature at 3 km?
A)-30°C
B)0°C
C)30°C
D)60°C

The unsaturated adiabatic lapse rate is approximately 10°C per kilometer. Since the air parcel is descending 2 km (from 5 km to 3 km), its temperature will increase by 20°C (2 km * 10°C/km). Therefore, the final temperature will be 10°C + 20°C = 30°C.
