The velocity of the sound is highest in A. Metal B. Air C. Water D. Vacuum

Metal
Air
Water
Vacuum

The velocity of sound is highest in solids, followed by liquids, and then gases. This is because the molecules in a solid are packed more closely together than the molecules in a liquid or gas, so sound waves can travel more quickly through a solid. In a

vacuum, there are no molecules to carry the sound wave, so sound cannot travel through a vacuum.
  • Option A: Metal is a solid, so sound travels fastest through metal.
  • Option B: Air is a gas, so sound travels slower through air than through metal.
  • Option C: Water is a liquid, so sound travels slower through water than through metal.
  • Option D: A vacuum is empty space, so sound cannot travel through a vacuum.
