Here is a table showing the approximate velocities of sound in different media at room temperature (25 °C):
| Medium | Velocity of sound (m/s) |
|---|---|
| Air | 343 |
| Water | 1,482 |
| Steel | 5,960 |
| Aluminum | 6,320 |
| Glass | 5,640 |
As you can see, the velocity of sound in air is much slower than in water, steel, aluminum, or glass. This is because air is much less dense and less elastic than these other media. The velocity of sound in water is faster than in air because water is denser and more elastic. The velocity of sound in steel, aluminum, and glass is even faster because these materials are even denser and more elastic than water.
