A parcel of air at the base of a mountain range has a temperature of 30 degrees Celsius .If the parcel of air moved 500 metres up the slope,its temperature would be approximately _______ degrees Celsius.

Question

Quizplus · Accepted Answer

As the parcel of air moves up the slope, it undergoes adiabatic cooling, which means its temperature drops by approximately 1 degree Celsius per 100 meters of ascent. So, at 500 meters up the slope, the temperature would drop by approximately 5 degrees Celsius. Therefore, the approximate temperature of the parcel of air at 500 meters up the slope would be 30 - 5 = 25 degrees Celsius. However, since 25 degrees Celsius is not one of the answer choices, the closest option is B, which is 27 degrees Celsius.
