If the atmospheric air is cooled because of expansion, the cooling is known as
A
Adiabatic
B
Lapse rate
C
Alto-cooling
D
Inverse cooling
Correct Answer: Adiabatic
If the atmospheric air is cooled because of expansion, the cooling is known as Adiabatic. An adiabatic process occurs without transfer of heat or mass of substances between a thermodynamic system and its surroundings. In an adiabatic process, energy is transferred to the surroundings only as work.
