Question

3.The matter that supports the sound is

called ________.

A. Medium

B. Temperature

C. Density

D. None of the above​

Answer 1

Ans. A

Sol. The speed of sound is not always the

same. Remember that sound is a

vibration of kinetic energy passed from

molecule to molecule. The closer the

molecules are to each other and the

tighter their bonds, the less time it takes

for them to pass the sound to each other

and the faster sound can travel. It is

easier for sound waves to go through

solids than through liquids because the

molecules are closer together and more

tightly bonded in solids. Similarly, it is

harder for sound to pass through gases

than through liquids, because gaseous

molecules are farther apart. The speed of

sound is faster in solid materials and

slower in liquids or gases.
