What is the temperature outside the plane if it is flying at an altitude of 8000m?

What is the temperature outside the plane if it is flying at an altitude of 8000m? On Earth at this time, the air temperature is +15 degrees C.

Before proceeding with the solution of the problem, the following rule should be remembered: with a rise for every 1 km upward, the air temperature drops by approximately 6 ° C. Thus, knowing this rule, we can calculate how the air temperature will change with increasing altitude. To do this, you must perform the following action:

8 × 6 = 48 ° С – the air temperature will drop.

Hence,

+15 – 48 = -33 ° C.

Thus, we learned that at an altitude of 8 km outside the plane, the air temperature will be -33 ° С.
