Question: 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)

Options:

  1. 30°C
  2. 24.5°C
  3. 27°C
  4. 22°C

Correct Answer: 24.5°C

Exam Year: 2020

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.

Questions & Step-by-Step Solutions

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)
  • Step 1: Understand that the lapse rate is the rate at which temperature decreases with altitude. In this case, it is 6.5°C for every kilometer (1000 meters).
  • Step 2: Convert the altitude from meters to kilometers. Since 1000 meters is equal to 1 kilometer, we will use this value.
  • Step 3: Calculate the temperature drop using the lapse rate. Multiply the lapse rate (6.5°C/km) by the altitude in kilometers (1 km): 6.5°C/km * 1 km = 6.5°C.
  • Step 4: Subtract the temperature drop from the sea level temperature. Start with the sea level temperature of 30°C and subtract the temperature drop: 30°C - 6.5°C = 23.5°C.
  • Step 5: Round the result to one decimal place if necessary. In this case, 23.5°C is already at one decimal place, but if rounding to the nearest whole number, it would be 24°C.
  • Lapse Rate – The rate at which temperature decreases with an increase in altitude, typically 6.5°C per kilometer in the troposphere.
  • Altitude and Temperature Relationship – Understanding how temperature changes with altitude is crucial for solving problems related to atmospheric conditions.
