In which of the following media does sound move the fastest at a particular temperature?
Iron
Sound travels fastest through solids like iron because their particles are closely packed with strong intermolecular bonds, allowing vibrations to transfer quickly from one particle to the next.
Sound travels slower in liquids like water than in solids, and slower still in gases like air, since particle spacing increases and bonding weakens across these states.
Sound cannot travel through a vacuum at all, as it requires a material medium to propagate.
Hence, the correct answer is Iron.
