B.) Sound changes as it travels through different states of matter.
C.) Sound does not change as it travels through different states of matter.
D.) Sound becomes clearer and louder as it moves away from its source.

Answer 1

Answer:

Sound is a form of energy produced and transmitted by vibrating matter. Sound travels in waves. When sound moves through matter (solid, liquid, or a gas), the molecules of the matter move backward and forward in the direction in which the wave is traveling. This movement is called a vibration. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together. Sound travels the lowest through gases because the molecules of a gas are farthest apart. In a vacuum sound cannot travel because there is no matter for it to move through.
