How does the speed of sound in sea water compare to the speed of sound in air?
A.
The speed of sound is slower in sea water because the molecules in sea water are closer to each other and more 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 less dense.


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

Answer 1

The correct answer is:

**D. 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 denser media (like sea water) compared to less dense media (like air) because the closer proximity of molecules facilitates quicker transmission of sound waves.
