Question
The data shows the speed of sound through air and sea water at 21°C.
Material: Air = 331 speed
Material: Sea water = 1,524 speed
How does the speed of sound in sea water compare to the speed of sound in air?
A.
The speed of sound is faster in sea water because the molecules in sea water are closer to each other and less dense.
B.
The speed of sound is slower in sea water because the molecules in sea water are closer to each other and less dense.
C.
The speed of sound is faster in sea water because the molecules in sea water are closer to each other and more dense.
D.
The speed of sound is slower in sea water because the molecules in sea water are closer to each other and more dense.

The correct answer is:
**C. The speed of sound is faster in sea water because the molecules in sea water are closer to each other and more dense.**
In general, sound travels faster in liquids than in gases due to the closer arrangement of molecules in liquids, which allows sound waves to transmit more efficiently. Sea water is denser than air, which contributes to the higher speed of sound in sea water compared to air.
