Q. If the temperature at sea level is 30°C, what is the approximate temperature at an altitude of 1000 meters, assuming a lapse rate of 6.5°C per kilometer? (2020)
A.
30°C
B.
24.5°C
C.
27°C
D.
22°C
Solution
Using the lapse rate of 6.5°C/km, the temperature drop at 1000 meters is 6.5°C. Therefore, 30°C - 6.5°C = 23.5°C, which rounds to 24.5°C.
Q. If the temperature at sea level is 30°C, what is the approximate temperature at an altitude of 3000 meters, assuming a lapse rate of 6.5°C per kilometer?
A.
15.5°C
B.
20°C
C.
10°C
D.
25°C
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, which rounds to approximately 15.5°C.
Q. 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)
A.
15.5°C
B.
18.5°C
C.
21.5°C
D.
24.5°C
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.
Q. If the temperature increases by 10°C, how much will the volume of a gas increase if the pressure remains constant? (2021)
A.
10%
B.
20%
C.
30%
D.
15%
Solution
According to Charles's Law, volume is directly proportional to temperature at constant pressure. A 10°C increase will result in a 10% increase in volume.
