It is known that at an altitude of 400 m above sea level, the temperature is +23 C.

It is known that at an altitude of 400 m above sea level, the temperature is +23 C. Determine the air temperature at 200 m above sea level and 0 m above sea level.

It is known that when the altitude changes by 1000 meters, the air temperature changes by 6 degrees Celsius. At the same time, with an increase in altitude, the air temperature decreases, and with a decrease, it rises.
a) Determine the temperature at an altitude of 200 m above sea level:
1. Determine the height difference: 400 m – 200 m = 200 m = 0.2 km
2. Determine the difference in air temperatures: 0.2 km × 6оС = 1.2оС
3. Determine the air temperature at an altitude of 200 m: 23оС + 1.2оС = 24.2оС

Answer: at an altitude of 200 m the air temperature is 24.2 ° C.

b) Determine the air temperature at a height of 0 m above sea level:
1. Let’s determine the difference in heights: 400 m -0 m = 400 m = 0.4 km
2. Determine the difference in air temperatures: 0.4 km × 6оС = 2.4оС
3. Determine the air temperature at a height of 0 m: 23оС + 2.4оС = 25.4оС

Answer: at a height of 0 m, the air temperature is 25.4 ° C.
