The data shows the speed of sound through air and water from the sea at 21°C.

Question

How does the speed of sound compare in sea water to the speed of sound in air?

The speed of sound is slower in sea water because the molecules in sea water are farther from each other and more dense.

Answer 1

The correct response is:

The speed of sound is faster in sea water because the molecules in sea water are closer to each other and more dense.

Sound travels faster in liquids than in gases because the molecules in liquids are closer together, allowing sound waves to transmit more efficiently. Additionally, sea water has a higher density than air, which also contributes to the increased speed of sound.
