The speed of sound depends on the temperature of the medium.
00:06
Why does the speed of sound depend on the temperature of the medium? well, we know that sound waves are composed of vibrating particles or molecules that transfer energy to their neighboring molecules.
00:22
We also know that when the temperature of the medium goes up, the molecules start moving faster and they start crashing into each other more frequently.
00:31
So the transfer of energy or the disturbance can travel faster if the temperature goes up.
00:39
The wave disturbance can travel faster to the medium because of the more frequent collisions.
00:46
And so the speed of sound increases.
00:49
If the temperature decreases, the speed of sound will decrease.
00:53
Now, sound can also travel through solids and liquids, but in solids and liquids, but in solids and the particles are typically closer together than they are compared to gases...
