Answer :
Final answer:
Condensation will begin at an elevation of 2000 meters, using the average environmental lapse rate to calculate the altitude where the temperature drops from 27°C to the dew point of 14°C.
Explanation:
The question asked is related to the process of air cooling and condensation as it rises up a mountain slope. The air at sea level has a temperature of 27°C, and its dew point at the condensation level is 14°C. To determine at what elevation condensation begins, we can refer to the environmental lapse rate, which is the rate at which air temperature drops with an increase in altitude. The average environmental lapse rate is approximately 6.5°C per 1000 meters. We need to calculate the difference in temperature from the starting temperature at sea level (27°C) to the dew point temperature (14°C), which is 13°C. Applying the environmental lapse rate, condensation would begin after the temperature drops by 13°C, which would occur after the air has risen:
- 13°C / 6.5°C per 1000 meters = 2 kilometers
So, condensation will begin at an elevation of 2000 meters.
