Question

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

Answer

Sound travels fastest in Iron (Solid).

Reason:
Sound travels faster in solids than in liquids and gases. This is because the particles in solids are packed tightly together, allowing the vibrations to pass from one particle to another more quickly.

Order of speed:
Iron > Water > Air
