Question

In which of the three media, air, water or iron, does sound travel fastest at a particular temperature?

Answer 1

1. Sound requires a material medium for its propagation.
2. The more densely the molecules are packed together, the more easily vibration travels through it.
3. The speed might vary with a change in temperature.
4. Speed of sound depends directly on elasticity, and solids have the highest elasticity.
5. In solids, sound travels faster as compared to liquids and gases.

Hence, at a particular temperature, sound travels fastest in solid.
