Question

for sound to travel, there must be molecules to vibrate. the closer the molecules are together, the faster sound travels. sound waves cause molecules to vibrate and bump into one another. for sound to travel, there must be molecules to vibrate. the closer the molecules are together, the faster sound travels. based on this information, what can you predict about sound waves and the medium? a. sound travels faster in steel than in water. b. sound travels faster in air than in water. c. sound travels faster in outer space than in air. d. sound travels faster in water than in steel.

Explanation:

Sound travels faster in mediums with closely - packed molecules. Steel has more closely - packed molecules than water, and water has more closely - packed molecules than air. Outer space has no molecules (a vacuum), so sound cannot travel there.

Answer:

A. Sound travels faster in steel than in water.
