Sound waves propagation in air exemplifies an ______________ process?
Correct answer: B. Adiabatic
- A. Isothermal
- B. Adiabatic
- C. Isometric
- D. None of these
Explanation
Sound propagation is rapid enough that there is essentially no time for heat transfer between the compressed air and its surroundings. The pressure changes therefore occur approximately adiabatically.
