Question

sound travels slower in colder air than it does in warmer air why does the speed of sound depend on air temperature

Answer 1

Air molecules have more energy at higher temperature which means they vibrate faster

Answer 2

Step-by-step explanation:

The speed of sound in the air mainly depends on temperature. At high altitudes, where it is much colder, sound travels slower. The higher the temperature, the faster the air molecules are moving to begin with, and the quicker they bump into each other as a sound wave passes through.
