Question

Решите задачу. Какая t воздуха у поверхности земли, если на высоте 4км она равна 15°С?

Answer 1

Ответ:

если температура воздуха с каждым километром вверх снижается на 6°С, то: 6•4+15=39, то есть температура воздуха на поверхности земли 39°С

Answer 2

Problem Analysis

To solve this problem, we need to find the temperature at the surface of the Earth given that it is 15°C at a height of 4 km. We can assume that the temperature decreases with increasing altitude due to various atmospheric factors.

Solution

The temperature at different altitudes can be calculated using the lapse rate, which is the rate at which temperature decreases with increasing altitude. The average lapse rate in the troposphere (the lowest layer of the Earth's atmosphere) is approximately 6.5°C per kilometer.

To find the temperature at the surface of the Earth, we can use the lapse rate to calculate the temperature difference between the surface and the given altitude of 4 km.

Let's calculate the temperature at the surface of the Earth:

1. Calculate the temperature difference between the given altitude and the surface: - Temperature difference = Lapse rate * Altitude - Temperature difference = 6.5°C/km * 4 km = 26°C

2. Subtract the temperature difference from the given temperature at 4 km to find the temperature at the surface: - Temperature at the surface = Temperature at 4 km - Temperature difference - Temperature at the surface = 15°C - 26°C = -11°C

Therefore, the temperature at the surface of the Earth is -11°C.

Conclusion

The temperature at the surface of the Earth, given that it is 15°C at a height of 4 km, is -11°C. This calculation is based on the average lapse rate in the troposphere, which is approximately 6.5°C per kilometer.
