Material Speed (m/s)
Air 331
Sea Water 1,524
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.
This is because sound travels faster in denser media, and in the case of sea water, the molecules are indeed more densely packed compared to air, allowing sound to transfer more quickly.
