which do sound waves travel fastest through?\n\nsolids\ngases\nmixtures\nliquids

Explanation:

Step1: Identify sound wave nature

Sound waves are mechanical longitudinal waves requiring a medium to propagate via particle collisions.

Step2: Compare particle density

Solids have the highest particle density and strongest intermolecular bonds compared to liquids and gases.

Step3: Determine propagation speed

Higher density and elasticity in solids allow vibrations to transfer more rapidly between adjacent particles.

Answer:

solids
