Answer 2

Calculating Temperature Difference and Altitude of the Aircraft

To determine the temperature outside the aircraft at an altitude of 2 km, we can use the standard lapse rate of the atmosphere, which is approximately 6.5°C per kilometer.

Given: - Surface temperature of the earth: +20°C - Temperature outside the aircraft: -12°C - Surface temperature of the earth at a different location: -6°C

First, let's calculate the temperature difference between the surface and the altitude of 2 km using the lapse rate.

The temperature difference can be calculated using the formula: Temperature difference = Lapse rate × Altitude

Using the given lapse rate of 6.5°C per kilometer: Temperature difference = 6.5°C/km × 2 km = 13°C

Now, we can calculate the temperature outside the aircraft at an altitude of 2 km: Temperature at 2 km altitude = Surface temperature - Temperature difference Temperature at 2 km altitude = +20°C - 13°C = +7°C

So, the temperature outside the aircraft at an altitude of 2 km is approximately +7°C.

Next, let's determine the altitude at which the aircraft is flying, given the temperature outside the aircraft and the surface temperature of the earth at a different location.

The temperature difference between the surface and the altitude can be calculated using the formula: Temperature difference = Lapse rate × Altitude

Using the given temperature difference of 14°C (from -6°C to -12°C): 14°C = 6.5°C/km × Altitude

Solving for altitude: Altitude = Temperature difference / Lapse rate Altitude = 14°C / 6.5°C/km ≈ 2.15 km

Therefore, the altitude at which the aircraft is flying is approximately 2.15 km.

In summary, the temperature outside the aircraft at an altitude of 2 km is approximately +7°C, and the altitude at which the aircraft is flying is approximately 2.15 km.
