As the temperature of the air increases, what happens to the velocity of sound? (Assume that all other factors remain constant.)Select one:a. It increases.b. It increases when atmospheric pressure is low and decreases when the pressure is high.c. It does not change.d. It decreases.e. It increases when atmospheric pressure is high and decreases when the pressure is low.

Respuesta :

Answer:

a. It increases

Explanation:

The sound is transmitted by the vibration of the particles in the air. If the temperature increase the particles have more energy and they can vibrate faster which makes that the velocity of the sound increase. So, as the temperature of the air increases, the velocity of sound increases.
