Dry adiabatic lapse rate is
A. 6.4° C/Km
B. 2.5° C/Km
C. 9.8° C/Km
D. 4.6° C/Km
Answer: Option C
Solution (By Examveda Team)
The dry adiabatic lapse rate is the rate at which the temperature of a parcel of dry air decreases as the parcel is lifted in the atmosphere.No heat is added or subtracted from the moving air parcel (adiabatic) and no moisture is condensing. The dry adiabatic lapse rate is 5.5°F per 1000 ft. or 9.8°C per km.
