The table below shows the speed of sound in water at different temperatures in salinities.
Which statement can be inferred about the speed of sound in freshwater and in seawater?
(1 point)
The speed of sound increases as a salinity of water decreases.
The speed of sound increases as the salinity of water increases.
Both temperature and salinity decrease the speed of sound in water.
O At 80°C, the speed of sound and freshwater and seawater will be the same.

Answer: "The speed of sound increases as the salinity of water increases."

Explanation: At each temperature the seawater values (e.g. 1,449 vs 1,403 m/s at 0°C; 1,546 vs 1,507 m/s at 30°C) are higher than the freshwater values, so increasing salinity raises sound speed. (Temperature also increases sound speed in both cases.)
