Answer:

3. False

Sound waves are vibrations of particles in media such as air, water, or metal. So it stands to reason that they cannot travel through space, where there are no atoms or molecules to vibrate.

4. False

Because sound moves faster in warm air than colder air, the wave bends away from the warm air and back toward the ground. That's why sound can travel farther in chilly weather. Of course, there's a lot more that makes winter mornings quiet than just the speed of sound.

5. False

Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. Sound waves travel over 17 times faster through steel than through air.
