Questions & Step-by-Step Solutions
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?
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 3000 meters is equal to 3 kilometers, we will use this value for our calculations.
Step 3: Calculate the total temperature drop by multiplying the lapse rate by the altitude in kilometers. This is done by taking 6.5°C/km and multiplying it by 3 km: 6.5 * 3 = 19.5°C.
Step 4: Subtract the temperature drop from the initial temperature at sea level. Start with the sea level temperature of 30°C and subtract the drop: 30°C - 19.5°C = 10.5°C.
Step 5: Round the final temperature to the nearest whole number if necessary. In this case, 10.5°C rounds to approximately 11°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 based on the lapse rate.
