Question

In cold winter night sounds travel slowly why

Answer 1

Answer:

Since heating those particles up increases their speed, this increases the speed of sound. If those molecules are cooled so that they are moving more slowly, sound waves are propagated more slowly by those molecules. ... Those particles are going slower in cold air.

Answer 2

In cold winter night sounds travels slowly because -

• The cold air molecules have less amount of heat energy and they are heavy than the hot air.

For this reason,the amount of molecular activities in the cold air is very low.

• This low amount of molecular activity of the air molecules makes the molecules more and more stationary.

• These stationary air molecules try to resist the propagation of the sound waves through them.

That's why sound waves travels slower in the cold air.

• As a conclusion,we can say that the temperature of the air is directly proportional with the sound velocity.
