Given a lapse rate of 3 degrees C/1000 meters and a temp of 20 degrees C at 0 meters:

A.What is the air sitting at 3,000 meters elevation?___degrees C

B.If a sample of air were lifted from 0 meters to 3,000 meters elevation, what would its new temp be?_____C(Assume no condensation is occuring.)

I don't undertsnad how to figure this out at all....

To understand how to solve these questions, we need to use the concept of the lapse rate. The lapse rate refers to the temperature change that occurs with increasing altitude in the Earth's atmosphere.

The given lapse rate is 3 degrees Celsius per 1000 meters. This means that for every 1000 meters increase in altitude, the temperature decreases by 3 degrees Celsius.

Now let's solve the questions:

A. What is the air temperature at 3000 meters elevation?

To find the temperature at 3000 meters, we need to determine how many 1000 meter increments we have from 0 meters to 3000 meters. In this case, it would be 3 increments (3000 meters / 1000 meters per increment = 3 increments).

Since the lapse rate is -3 degrees Celsius per increment, we can multiply the number of increments (3) by the lapse rate (-3 degrees Celsius) to calculate the temperature change. -3 * 3 = -9 degrees Celsius.

Therefore, to find the air temperature at 3000 meters elevation, we need to subtract the temperature change (-9 degrees Celsius) from the initial temperature (20 degrees Celsius):
20 degrees Celsius - 9 degrees Celsius = 11 degrees Celsius.

Therefore, the air temperature at 3000 meters elevation would be 11 degrees Celsius.

B. If a sample of air were lifted from 0 meters to 3000 meters elevation, what would its new temperature be? (Assume no condensation is occurring.)

Since we already calculated the temperature change of 3 increments (-9 degrees Celsius), we need to subtract this temperature change from the initial temperature of 20 degrees Celsius:

20 degrees Celsius - 9 degrees Celsius = 11 degrees Celsius.

Therefore, if a sample of air were lifted from 0 meters to 3000 meters elevation, its new temperature would also be 11 degrees Celsius.
