solid; spread out
solid; close together
gas; spread out
gas; close together

can; there are no particles to get in the way
can not; there are no sound particles
can; sound is it's own particle
can not; there are no particles to vibrate
Humans can hear frequencies as low as (a) Hz
Humans can hear frequencies as high as (a) Hz
How does sound travel at the particle level?
Sound bounces off each particle to move toward its destination.
Sound moves between the particles. Particles slow down the wave.
Sound moves via collisions of particles. Sound is the kinetic energy passing between particles as they collide.
Sound moves via absorption by particles which then emit energy in the direction of the destination.
Humans can hear sound by ___.
sound particles enter the ear and go to sound receptors in the brain
sound particles strike the eardrum, creating signals that get sent to the brain
sound waves strike the eardrum, creating signals that get sent to the brain
sound waves enter the ear and go to sound receptors in the brain
How is intensity and frequency of sound related?
As frequency goes up, the intensity goes up.
As frequency goes up, the intensity goes down.
Frequency and intensity are independent of each other.
Frequency and intensity are two words that describe the same thing.
How is sound created?
The source of the sound produces sound particles and sends them outwards.
The source of the sound transforms the particles in the air into sound particles.
The source of the sound vibrates and forces particles to carry the sound away.
The source of the sound vibrates and collides into particles nearby, causing a series of collisions between particles.
