The speed of sound in water is greater than the speed of sound in air .
For example, at 20 °C and 1 ATM pressure, the speed of sound in air is 343 m/s, and its speed in water is 1482 m/s.
In general, the
speed of sound in a medium = (bulk modulus of the medium/ its density)^0.5
where the bulk modulus indicates how compressible the medium is; the greater the bulk modulus, the more incompressible the medium is.
So,
although water has a density much greater than that of air, water is also much more incompressible than air.
When you solve for the speed of sound for both water and air using the above formula, you will find that it is greater in water.

Is the speed of sound greater or lesser different altitudes?
It changes depending on the altitude so at some altitudes the speed of sound is greater and at others it is less.
How speed of sound of pure water compare with the speed of sound in ocean water?
In salt water that is free of air bubbles or suspended sediment, sound travels at about 1560 m/s. The speed of sound in seawater depends on pressure (hence depth), temperature (a change of 1 °C ~ 4 m/s),and empirical equations have been derived to accurately calculate sound speed from these variables. In pure water the speed of sound is less than in ocean water.
Do sound waves travel slower in rubber water air or glass?
The speed of a sound wave depends on two properties of a medium, density and elasticity.Specifically, for basically all substances, the speed of sound equals the square root of the ratio of the elastic constant divided by the density.Glass has a very large elastic constant but not an exceptionally large density, so it would be expected to have a speed of sound similar to or greater than most solids and that is much greater than the speed of sound in air. Rubber is lighter than most solids, but has a small elastic constant. (That is the whole point of a rubber band, i.e. easy to stretch.) One would expect the very small elastic constant to make the speed of sound in rubber far less than other solids. Given that its density is far greater than air, however, the speed of sound in rubber is going to be smaller than in air. Of course, the term "rubber" is applied to many different materials and so the conclusions related to rubber may not be broadly valid.
Why is the speed of sound in water faster than in air?
Sound waves travel faster in water than in air because of the particle configuration. The particles in water are closer to each other compared to the particles in air. Since sound travels with one particle bumping into another and causing it to vibrate, sound waves travel faster in water.
Is water more or less dense than oil?
The density of water is greater than that of oil.
Is the speed of sound greater or lesser different altitudes?
It changes depending on the altitude so at some altitudes the speed of sound is greater and at others it is less.
Does sound while passing from air to water also bend towards normal?
The law of refraction is a general result of plane waves traveling from one medium to another. Consider light. The speed of light in water is LESS than its speed in air, and it bends toward the normal (refracts). The speed of sound, however, is GREATER in water than it is in air, thus its "index of refraction" is less than one (i.e. sound bends away from the normal when traveling from air to water).
Why is the speed of sound in the water louder at night?
A speed can't be louder or less loud. The sound itself can be louder; or the speed can be faster.
If you are under water and you speak will it take more time for the sound to travel or less time?
It will take less time.....Because the speed of sound in water is more than that in air :)

Why was Chuck Yeager's altitude an important element when he broke the sound barrier?
Further up in the atmosphere there is less resistance for a moving object to overcome. Less drag on his vessel meant greater speed. Does that theory FLY? (ha ha) --- Also, the speed of sound is higher at sea level due to the air's density being greater.
Why is the velocity of sound greater in solids than in gas or liquid?
The speed of sound is greater in solids because the molecules of solids are so much closer together - it takes less time, then, for the sound waves to transfer from one molecule to the next, and to the next, and so on.
How can the movement of molecules help explain why hot water evaporates faster?
If the water is cold, that means that water molecules have small speed, in hot water, molecules have greater speed, thus greater energy, and need less energy than cold water to be kicked out through the surface.
When is the speed of sound near the ground less than the speed of sound higher up?
If the speed of sound near the ground is less than the speed of sound higher then in this special case the temperature at the ground must be less than the temperature higher up. Usually the temperature at the ground is warmer than the temperature high up in the sky. The speed of sound changes mainly with the temperature.
What do you called if the Speed of objects less than the speed of sound?
Subsonic
How fast subsonic speed?
Less than the speed of sound in that medium.
How fast is mach 1000?
Mach 10 is equivalent to 3,402.9 meters per second. It is about 7,000 miles per hour. At Mach 10, an aircraft could circumnavigate the earth in less than four hours. The Mach number is a measure of how fast an object is travelling relative to the speed of sound. The Mach number is calculated by dividing the speed of an object by the speed of sound. Speed of sound is about 760mph
