A parcel of air at 5 km. and an initial temperature of 10°C altitude descends to 3 km altitude at the unsaturated adiabatic lapse rate. What is the temperature at 3 km?

Answer:

30 degrees Celsius

Explanation:

With unsaturated adiabatic lapse rate water vapour does not have to change state from gaseous to liquid.

Lanuel

The temperature of this parcel of air is equal to 30°C.

Given the following data:

  • Initial altitude = 5 km.
  • Initial temperature = 10°C.
  • Final altitude = 3 km.

What is an adiabatic lapse rate?

An adiabatic lapse rate can be defined as the rate at which the temperature of a parcel of air changes with respect to either the expansion or compression that is associated with altitude (elevation) change, provided that the process is adiabatic.

This ultimately implies that, there is no heat exchange between the a parcel of air and its surroundings during an adiabatic process. For an unsaturated parcel of air, the lapse rate is equal to 3°C per 1000 feet and this is generally referred to as the dry adiabatic lapse rate (DALR)

In conclusion, at 3 km, the temperature of this parcel of air would be equal to 30°C.
