Question

The phenomenon of sound propagation in air is

• A. Isothermal process
• B. Isobaric process
• C. Adiabatic process
• D. None of these

Answer 1

Answer: (C)

Adiabatic process

the point that there is a local change in temperature due to the compression and rarefaction half$-$ cycles of the waveform and that the these changes occur so quickly that no heat can enter or leave the cycle$,$

So$,$ it callesan adiabatic process$.$

Hence,

option $\left(C\right)$ is correct answer.
