At the surface of the Earth, the air temperature is + 18C. Travelers ascended in a balloon to a height of 2500 meters. What will the thermometer read in the ball basket?

In order for all calculations to be correct, you need to remember the following: with a rise for every 100 meters, the air temperature decreases by 0.6 ° C. We know that the balloon has risen 2500 meters. This is enough to find out how many times the air temperature will change. To do this, run:

2500 ÷ 100 = 25.

Means,

25 × 0.6 = 15 ° С – the air temperature will drop.

To calculate the air temperature at an altitude of 2500 m, you must:

+18 – 15 = + 3 ° C.

Thus, at an altitude of 2500 meters, the thermometer will show + 3 ° С.
