The best option would be:
b) The speed of sound increases as the salinity of water decreases.
This can be inferred from the table, as we can see that at each temperature, the speed of sound in seawater (which has a higher salinity than freshwater) is higher than the speed of sound in freshwater.
Question
The table below shows the speed of sound in water at different temperatures and salinities.
Speed of Sound in Water at Different Temperatures and Salinities
Temperature (°C) 0 10 20 30
Speed of sound in freshwater (ms
) 1,403 1,447 1,481 1,507
Speed of sound in seawater (ms
) 1,449 1,490 1,522 1,546
Which statement can be inferred about the speed of sound in freshwater and in seawater?
Which of the following is the best option?
a) Both temperature and salinity decrease the speed of sound in water.
b) The speed of sound increases as the salinity of water decreases.
c) At 80°C, the speed of sound in freshwater and seawater will be the same.
d) The speed of sound increases as the density of water increases.
