Question 1144785: As dry air moves upward, it expands and, in so doing, cools at a rate of about 1oC for each 100-meter rise, up to about 12 km. If the ground temperature is 10oC on the ground, what range of temperatures can be expected if an airplane takes off and reaches a maximum height of 4 km? (1 km = 1000 meters Answer by ikleyn(52787) (Show Source):
4 kilometers is 40 times 100 meters.
So, the air temperature at the height of 4 km is 40 degrees of Celsius below than 10 degrees of Celsius.
ANSWER. At the height of 4 km, the air temperature is 10 - 40 = -30 degrees of Celsius, under given conditions.
