Question

Quizplus · Accepted Answer

The flow of air (or any fluid) is directly proportional to a pressure gradient, meaning that the greater the difference in pressure between two points, the greater the flow of air between those points. However, this flow decreases as the resistance of the system increases, meaning that it becomes more difficult for the air to flow through narrower or more obstructed pathways. Therefore, choice A is the correct answer.
