Q. Sound velocity is usually larger in solids than in liquids and gases because:

  • (A) solids are more elastic than liquids and gases
  • (B) solids are less elastic than liquids and gases
  • (C) volumetric expansion coefficients of liquids and gases are higher than solids
  • (D) frequency of sound waves decreases in solids due to Doppler shift
✅ Correct Answer: (A) solids are more elastic than liquids and gases
Explanation: A substance is labelled more elastic if it offers greater resistance to deformation than other bodies, so that it can be stretched less than others.
