How does the speed of sound in water compare with speed of sound in air?

Answer:
Speed of sound in water is c = 1480 m/s. It is affected by the oceanographic variables of temperature, salinity, and pressure.

Speed of sound in air is c = 343 m/s at 20°C = 68°F. The speed of sound changes clearly with temperature, a little bit with humidity - but not with air pressure (atmospheric pressure).

Speed of sound in water is faster than in air.
