Question

25. Explain why the speed of sound is faster in solids than in gases. Include two other factors Chapter 17 says the speed of sound can depend on.

Answer 1

In solids, particles or atom are very closely arranged compared to gasses. When these particles are arranged in such proximity, vibrations from sound are very easily transmitted from one particle to another in the solid. Hence, the sound vibrations can travel through the solid medium more quickly than through a gas medium.
Speed of sound also depends on its frequency and the wavelength.
