# Calculate the air temperature at the top of the mountain with a height of 3500 m, if at the foot of the mountain

**Calculate the air temperature at the top of the mountain with a height of 3500 m, if at the foot of the mountain, located at an altitude of 500 m above sea level, the temperature is +20 ° C**

To solve the problem, it is first necessary to determine the relative height of the mountain peak.

To do this, subtract the height of its foot from the full height of the mountain.

We get:

3500 – 500 = 3000 meters.

We accept a temperature change of one km equal to 6 degrees Celsius.

In this case, the temperature difference between the top and the foot will be:

3000 m = 3 km.

3 * 6 = 18 degrees.

Find the temperature at the top of the mountain.

To do this, subtract the temperature difference from the air temperature at the foot of the mountain.

20 – 18 = 2 degrees Celsius.
