A rising parcel of air that does not exchange heat with its surroundings is an example of
A) isothermal ascent.
B) an adiabatic process.
C) forced lifting.
D) advection.

Question

Quizplus · Accepted Answer

An adiabatic process is a thermodynamic process in which there is no heat exchange between the system and its surroundings. In the context of atmospheric science, an adiabatic process occurs when a parcel of air rises and cools due to a decrease in pressure. As the air rises, it expands and does work on its surroundings, which causes it to cool. Conversely, if a parcel of air sinks, it is compressed and heats up due to an increase in pressure.
