Question

how does the speed of sound vary with the temperature​

Answer 1

Explanation:

Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy, thus they can vibrate faster. Since the molecules vibrate faster, sound waves can travel more quickly. ... The speed of sound is also affected by other factors such as humidity and air pressure.

Answer 2

Answer:

Temperature affects the speed of sound by changing the density of the medium in which a sound wave travels. In most cases, when the temperature of a medium increases so does the speed of sound through that medium.

Sound waves require a medium in order to travel. A medium can be a solid, liquid, or a gas such as air.

The speed of sound depends on both the elasticity and density of the medium. When the elasticity increases and density decreases of a medium, sound is allowed to travel faster. Higher temperatures lower the density of a medium, which puts less resistance on the sound waves and allows the sound to travel faster.
