Question
Why does sound travel slower in colder temperatures?Question 15AnswerA.Cold air can increase the elasticity of the mediumB.Cold air absorbs sound energy that is warmC.Cold air is denserD.Cold air has scattered molecules
Solution
The speed of sound is affected by the temperature of the medium through which it travels. In colder temperatures, the molecules in the air are closer together, making the air denser. This increased density actually slows down the speed of sound because the sound waves have to move a greater number of molecules to propagate the sound. Therefore, the correct answer is C. Cold air is denser.
