6. The more dense a liquid becomes, the faster sound travels in it. The data in the table below show the speeds at which sound travels in different liquids:

in which medium does sound travel faster.

The bulk modulus of water is 0.210 × 1010 N/m2 and the density is 1000 kg/m3. The speed of sound in water is

The speed of sound is dierent in dierent media. For example, in water it is ~1500 m/s. Draw a model to explain why sound propagates faster in water. Based upon your model, predict whether or not the speed of sound would be faster or slower through a wooden door than water.
