Question: If the temperature at sea level is 30°C, what would be the approximate temperature at an altitude of 3000 meters, assuming a lapse rate of 6.5°C per kilometer? (2022)

Options:

1. 15.5°C
2. 18.5°C
3. 21.5°C
4. 24.5°C

Correct Answer: 18.5°C

Exam Year: 2022

Solution:

Using the lapse rate of 6.5°C/km, the temperature drop at 3000 meters is 6.5 * 3 = 19.5°C. Therefore, the temperature at 3000 meters is 30°C - 19.5°C = 10.5°C.
