If an unsaturated air parcel with a temperature of 20 degrees c rises, forms a non-precipitating cloud, then returns to its original altitude, a. the parcel's final temperature will be less than 20 degrees c b. the parcel's final temperature will be greater than 20 degrees c c. the parcel's final temperature will be exactly 20 degrees c

The answer is: b. The final temperature of the package will be greater than 20 degrees C.

Explanation:

When an airbag with a temperature of 20 degrees Celsius is forced to pass through a mountain range of 2,500 m. of altitude. The dew point is reached at 900 m. and clouds form. The air is cooled approximately 1 degree Celsius every 100 meters to reach the dew point.

When the air begins to descend, its temperature rises at a rate of approximately 0.5 degree Celsius every 100 meters.

Therefore, the temperature will rise to 28 degrees Celsius after the descent.

The answer is: b. The final temperature of the package will be greater than 20 degrees C.

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
