The Speed of Sound Quick Check

Based on the table, which statement describes the relationship between temperature and the speed of sound in water?

Sound travels faster in warmer water, both in fresh water and sea water.

Why does sound travel the slowest in air?

The distance between molecules of air is greater than for molecules of water.

A student conducts an experiment in which sound waves pass through air and then through water. Which statement describes the wave speed as it passes from air to water?

The speed of sound increases.

Which statement correctly compares the speed of sound in solids and gases?

The speed of sound is generally faster in solids than in gases, because solids are denser than gases.

The speed of sound through diamond is about 12,000 m/s. The speed of sound through wood is about 3,300 m/s. Which statement explains why the speed of sound is different through these materials?

They have different rigidities.
