To find:
In which state of matter does the sound travel faster.
Step-by-step explanation:
The sound is a wave. Sound carries energy from one point in the medium to another through vibrations.
The vibrations can pass through more easily when the molecules in the medium are tightly held.
The molecules are very loosely held in the gas. The molecules are held more closely in liquids compared to gas. In solids, the molecules are packed very tightly compared to the other two states of matter.
Final answer:
Thus sounds travel fastest in solids.
Therefore the correct answer is option C.
