As atmospheric pressure increases, what happens to the velocity of sound? (Assume that all other factors remain constant.)
A) It increases on warm days and decreases on cold days.
B) It increases.
C) It does not change.
D) It decreases.

Question

Quizplus · Accepted Answer

The velocity of sound in air is primarily determined by the temperature of the air, not by the atmospheric pressure. Therefore, changes in atmospheric pressure, assuming all other factors (especially temperature) remain constant, do not affect the velocity of sound.
