The propagation of sound through air is a(n):
Correct answer: B. Adiabatic process
- A. Isothermal proces
- B. Adiabatic process
- C. Isobaric process
- D. Isochoric process
Explanation
The propagation of sound through air is an adiabatic process because sound waves travel through air with minimal exchange of heat with the surroundings. Adiabatic processes involve changes in pressure and volume without the exchange of heat.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
