A sound wave is passing through air column in the form of compression and rerefactions. In consecutive compressions and rerefactions.

Options

A. density remains constant
B. Boyles law is obeyed
C. bulk modulus of air oscillates
D. there is no transfer of heat.

Explanation

### Step-by-Step Solution:

1. **Understanding Sound Waves**: Sound waves are mechanical waves that travel through a medium (like air) in the form of compressions and rarefactions. Compressions are regions where particles are close together, while rarefactions are regions where particles are spread apart.

2. **Behavior of Air During Sound Propagation**: As sound waves travel through air, the pressure and density of the air oscillate. However, these oscillations occur rapidly, and the air particles do not have enough time to transfer heat between compressions and rarefactions.

3. **Heat Transfer in Air**: Air is a poor conductor of heat. This means that even if there are changes in pressure and density due to sound waves, the heat generated in compressions does not effectively transfer to the rarefactions.

4. **Conclusion**: Since the time interval between compressions and rarefactions is very small and because air does not conduct heat well, we conclude that there is no significant transfer of heat from the compressions to the rarefactions in the sound wave.

### Final Answer:
There is no transfer of heat from compression to rarefaction in a sound wave traveling through air.
