Speed of sound is maximum in which among the following? A) Gases B) Vaccum C) Liquids D) Solids

Speed of sound is maximum in solids and decreases from solids to liquids and liquids to gases. Sound can’t travel through a vacuum. Sound travels at different speeds depending on what it is travelling through. Temperature also affects the speed of sound.

Explanation:

The molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. Sound moves the slowest through a gas. That’s because the molecules in a gas are spaced very far apart. Sound travels faster in liquids than in gases because molecules are packed more closely together.

  • When a vibration begins, the solid molecules immediately collide, and the compression wave travels rapidly.
