Speed of Sound in Water at Different Temperatures and Salinities
Temperature (°C) 0 10 20 30
Speed of sound in freshwater ( m / s ) 1,403 1,447 1,481 1,507
Speed of sound in seawater ( m / s ) 1,449 1,490 1,522 1,546
Which statement can be inferred about the speed of sound in freshwater and in seawater?
(1 point)
Responses
The speed of sound increases as the salinity of water decreases.
The speed of sound increases as the salinity of water decreases.
Both temperature and salinity decrease the speed of sound in water.
Both temperature and salinity decrease the speed of sound in water.
The speed of sound increases as the density of water increases.
The speed of sound increases as the density of water increases.
At 80°C, the speed of sound in freshwater and seawater will be the same.
The correct statement that can be inferred about the speed of sound in freshwater and seawater is:
Both temperature and salinity decrease the speed of sound in water.
