Answer:Sound travels faster in water than in air because of the difference in the density and elasticity of the two mediums. Density:Water molecules are much closer together than air molecules. This means that sound waves have less distance to travel between molecules in water, allowing them to propagate fasterElasticity: Water is more elastic than air. This means that water molecules can more readily return to their original position after being disturbed by a sound wave. This rapid response contributes to the faster speed of sound in water.Think of it like this: Imagine a line of people holding hands. If you push the first person, the force will travel down the line quickly because the people are close together. Now imagine the same line, but the people are spread far apart. The force will take longer to travel down the line.The same principle applies to sound waves. In water, the molecules are closer together, so the sound wave travels faster.
