It is 45°C at sea level. What will the temperature be at 5500 meters? Use the normal lapse rate.

9.25°C

Explanation:

As you move higher from sea level, the temperature drops at an average rate. This average rate at which the temperature drops is known as the lapse rate.

This rate is 6.5 °C per 1000 m.

Temperature at 5,500m has dropped by;

= 6.5 *

= 35.75 °C

Temperature has decreased by 35.75 °C.

Temperature at 5,500m above sea level is;

= 45 - 35.75

= 9.25°C
