Question

The temperature of the air in a valley begins to increase after the sun comes up and heats the valley floor. What will

happen to the velocity of sound in this valley?
-The velocity will increase
-The veocity will decrease
-The velocity will not change
-The velocity will drop to zero.​

Answer 1

The velocity will increase.

Step-by-step explanation:

Wave velocity and the temperature of the medium are directly proportional so if the temperature increases, the velocity will increase.

Answer 2

Step-by-step explanation:

I think it will increase a little bit ... just image ... if the temperature is 0, the velocity will be 0 too. because the vibration of atom is so weak and the sound cant progation.
