Which statement about the effect of temperature on the speed of sound is correct?
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
Changes in temperature have no effect on the speed of sound.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound increases because the medium becomes denser.

The correct statement about the effect of temperature on the speed of sound is:
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
To understand why this is the correct statement, let's explore the underlying physics. Sound is a mechanical wave that moves through a medium, typically air. The speed of sound is determined by the medium's elasticity and its density.
When the temperature of the medium increases, the molecules in the medium gain more kinetic energy, leading to an increase in their average speed. This increased molecular speed results in more frequent collisions between molecules.
In a sound wave, molecules in the medium vibrate back and forth, transferring energy from one molecule to another through these collisions. When there are more collisions happening, the energy transfer occurs more rapidly, resulting in an increase in the speed at which the sound wave propagates through the medium.
Therefore, as temperature increases, the speed of sound also increases because the molecules in the medium collide more frequently.
