How does the temperature of a medium affect the speed of sound waves traveling through it?

The correct answer highlights the relationship between temperature and the speed of sound in a medium. As temperature increases, the kinetic energy of the molecules in the medium also increases. This heightened energy means that the molecules can vibrate and collide more frequently and with greater force. As a result, sound waves can travel faster through warmer materials.

In gases, for instance, this relationship is particularly evident; warmer air allows sound to move more quickly than cooler air because the increased temperature enhances the frequency and energy of molecular collisions that propagate sound waves.

Understanding this principle is crucial in physics and engineering, as it affects applications ranging from acoustics in buildings to communication technologies. The temperature's influence on sound transmission is significant, making it essential to consider in scenarios involving changes in environmental conditions.
