Question

In which medium sound travels faster ?

• A. Gas
• B. Liquid
• C. Solid
• D. None of these

Answer 1

Answer:

C. Solid

Note:

• In solids, the distance between molecules is less. They are located next to each other.

• That means solids are denser than gases and liquids.

• Therefore, the molecules quickly collide with each other and transfer vibrational energy.

• Similarly, in liquids the molecules are closer together than in gases. Therefore, sound travels the slowest in gases and fastest in solids.
