How does sound travel?

Moves by vibrations

Must have a medium to transfer sound energy

Closeness of particles determine the speed of sound.

The closer particles are the faster the vibrations get passed on.

solids have a higher density

particles of matter are closer together

particles of matter don't have to travel far to pass on the vibrations

all of these choices

are less dense than solids

are more dense than gases

transfer vibrations faster than gases

all of these

it is more dense than solids and liquids

gas particles are too far apart they don't transfer vibrations

have to move farther distances to pass on vibrations

they aren't made

of matter

liquids

gases

solids

speeding up the particles of matter

allowing vibrations to move faster through the heated medium

affect the speed of sound transfer

all of these

a pillow

a bedroom curtain

a whiteboard

a ceiling tile

sound waves have to be reflected off of an object

sound waves have to be absorbed by an object

sounds have to hit a hard smooth surface

sound waves need to hit a soft, uneven material
