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