Final answer:
Steel has the highest ability to conduct sound, followed by water, then air.
Step-by-step explanation:
Sound travels differently in different materials based on their ability to conduct sound waves. The order of materials from highest to lowest ability to conduct sound is: Steel, Water, Air.
Steel has the highest ability to conduct sound because it is a dense material with high rigidity.
Water has a lower ability to conduct sound compared to steel because it is less dense and less rigid.
Air has the lowest ability to conduct sound compared to steel and water because it is a less dense and less rigid medium for sound waves.
