A) the absolute pressure will be 2p.
B) the absolute pressure will be less than 2p.
C) the absolute pressure will be greater than 2p.
D) the gauge pressure will not change.
E) the gauge pressure will increase but will not double.

Question

Quizplus · Accepted Answer

The absolute pressure at a depth in a fluid is given by the sum of atmospheric pressure and the gauge pressure (which is the product of fluid density, gravitational acceleration, and depth). Doubling the depth doubles the gauge pressure, but since absolute pressure includes atmospheric pressure, it will be less than 2p.
