The velocity of the wave also increases, because molecules at higher temperatures have more energy.

Answer : The velocity of a sound wave increases in the air if the temperature of the air increases.

Explanation : If the temperature of the air increases then the velocity of a sound wave is increases in the air. because at high temperature , air molecules have more energy and they vibrate very fast.

So, we can say that air molecules vibrate very fast then the sound waves travel very quickly.
