Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem …

Textbook Question

Chapter 19, Problem 31A

In a deep dive, a whale is appreciably compressed by the pressure of the surrounding water. What happens to the whale’s density?

Expert Solution & Answer

To determine

To explain: Effect on the density of the whale when it deep dives.

Answer to Problem 31A

When a whale deep dives, then it gets denser.

Explanation of Solution

Introduction:

Any object sinks in the water when the density of the object is greater than the density of the water.

When a whale deep dives, then it compresses the pressure of the surrounding water. This way density of the whale increases, which helps in sinking deep inside the water.

Conclusion:

Thus, when a whale deep dives, then it gets denser.
