Q: Which of the following statements is true? The velocity of sound is
  • A. less in summer than winter
  • B. same in winter and summer
  • C. is not dependent on the weather
  • D. more in summer than winter
Correct Answer: Option D - The velocity of sound is greater in summer than in winter. Because the speed of sound increases with the temperature of the medium. The speed of sound 0.61 m/s when the temperature increases in the air at 1°C. The velocity of sound waves is the lowest in gases and the highest in solids.
