As air in the figure above moves from A to B, what will happen to its temperature?

Question

Quizplus · Accepted Answer

As the air moves from A to B, it is ascending in altitude. This means that it is moving into an area of lower atmospheric pressure. As the pressure decreases, the air expands and cools adiabatically (without gaining or losing heat). This process is known as adiabatic cooling and results in a decrease in temperature. Therefore, the correct answer is A, it will decrease.
