Which statement about the effect of temperature on the speed of sound is correct? (1 point)
Changes in temperature have O no effect on the speed of sound.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound increases because the medium becomes denser.
