Question

The data displays the velocity of sound in air, sea water, and steel at a temperature of 21°C.

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

The velocity of sound is reduced in sea water because the molecules in sea water are more closely arranged and denser.

The velocity of sound is greater in sea water because the molecules in sea water are more closely packed and denser.
The velocity of sound is greater in sea water because the molecules in sea water are more closely packed and denser.

The velocity of sound is greater in sea water due to the closer proximity and lower density of molecules in sea water.

Answer 1

The correct response is:

The velocity of sound is greater in sea water because the molecules in sea water are more closely packed and denser.

Sound travels faster in denser mediums, and sea water, being more dense than air, allows sound to travel more quickly through it.
