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

Question

Quizplus · Accepted Answer

The unsaturated adiabatic lapse rate is approximately 10°C per kilometer. Descending from 5 km to 3 km is a 2 km descent, so the temperature increases by 20°C from the initial 10°C, resulting in a final temperature of 30°C.
