Chapter 24, Problem 12A

What generally happens to the temperature of sinking air?

To determine

The temperature of sinking air.

Explanation of Solution

Introduction:

Temperature is a measure of how cold or hot a body is. The temperature is associated with the internal energy of the system. The first law of thermodynamics governs the change in the internal energy when work is done and heat is added to the system.

When the air sinks, itcompresses. The work is done on the system, internal energy of the system increases and hence, the temperature rises.

Conclusion:

The temperature of sinking air increases as it compresses.
