The speed of sound is faster in colder air?

Question

The speed of sound is faster in colder air?

Answer 1

In fact, speed of wound travels faster in warm air.

Sound travels in air through the collision of air particles.

In warm air, the collisions are more frequent, meaning that sound travels faster than in cold air where the particles have lesser energy and collisions are less frequent.

I hope I have answered your question.

Answer 2

yes. speed of sound is more in cold air because, the air is more denser. so the particles will be closer. the energy can be transmitted faster. also, the molecules in cold air will not have such a fast random motion as in warm air. so the energy will not be cancelled out.
