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.
Q. If the total number of members in the Lok Sabha is 545 and the number of members from the Scheduled Castes is 84, what percentage of the Lok Sabha members are from the Scheduled Castes?
A.
15.4%
B.
16.5%
C.
14.5%
D.
18.0%
Solution
Percentage of Scheduled Castes = (84/545) * 100 = 15.4%
Q. If the total number of votes in an election is 1,000,000 and the winning candidate receives 55% of the votes, how many votes did the winning candidate receive?
A.
550,000
B.
500,000
C.
600,000
D.
450,000
Solution
55% of 1,000,000 = 0.55 * 1,000,000 = 550,000 votes.
Q. If the total number of votes in the Lok Sabha election is 1,000,000 and the winning candidate receives 45% of the votes, how many votes did the winning candidate receive?
A.
450,000
B.
400,000
C.
500,000
D.
550,000
Solution
Votes received by winning candidate = 45% of 1,000,000 = 0.45 * 1,000,000 = 450,000.
