Question

which of the following can sound travel through? solid gas liquid all of the above

Explanation:

Sound is a mechanical wave that requires a medium to travel. Solids, liquids, and gases all act as media for sound propagation. In solids, particles are closely packed, allowing sound to travel faster. In liquids, particles are less dense than in solids but still allow sound transmission. In gases, particles are widely spaced, but sound can still travel through them (e.g., we hear sounds in air). So sound can travel through all three states of matter.

Answer:

D. all of the above (assuming the options are labeled A: solid, B: gas, C: liquid, D: all of the above; if the original options have different labels, adjust accordingly, but based on the content, the correct choice is the one stating "all of the above")
