assume you lift a parcel of air dry adiabatically to 1500m. assuming no other factors influence this parcel, how much will its temperature decrease?
a 7.5℃
b 15℃
c the parcels temperature would actually increase
d 10℃
e 12.5℃

Explanation:

Step1: Recall dry - adiabatic lapse rate

The dry - adiabatic lapse rate is 10°C per 1000m.

Step2: Calculate temperature change

We have a height change of 1500m. Using the formula $\text{Temperature change}=\text{Lapse rate}\times\text{Height change in km}$. First, convert 1500m to 1.5km. Then, $\text{Temperature change}=10^{\circ}C/km\times1.5km = 15^{\circ}C$.

Answer:

B. 15°C
