Chapter 20, Problem 33A

How would the density of air at the bottom of a deep mine shaft compare to the density of the atmosphere at the surface of the ground?

To determine

To compare: The density of air at the bottom of a deep mine shaft compared to the density of the atmosphere at the surface of the ground.

Answer to Problem 33A

The air at the bottom of a deep mine shaft is denser.

Explanation of Solution

Introduction:

With the decreasing depth, the pressure is more exerted on the surrounding air.

The air at the bottom of a deep mine shaft is deep underground and has a lesser volume of air. Since the air is highly compressed with the depth. The more depth increases, the more pressure is exerted on the air.

Conclusion:

Thus, the air is denser at the bottom of a deep mine shaft.
