Question

which material does sound travel the fastest? gases liquid solid

Explanation:

Sound travels fastest in solids because the particles in solids are closely packed, allowing sound waves (which are mechanical waves requiring a medium) to transfer energy more quickly through particle vibrations compared to liquids (particles less closely packed) and gases (particles far apart and moving randomly).

Answer:

solid (the option labeled "solid" or the right - most option if we consider the three options: gases, liquid, solid)
