Marina’s brother turned his speakers up so loud that it shook the walls and made a picture
frame fall to the floor. Their mom asked, “How can a loud sound make something fall?”
What is the best explanation for Marina to give to her mom?
Vibrations from the music transferred mechanical energy through the walls
Loud music created a magnetic field that attracted the picture to the floor.
The pitch of the music was too high to transmit energy
The electrical energy from the speakers transformed into thermal energy.
Tamara wondered how the temperature of air affects the speed of sound. In her research, she found the following data table.
What can Tamara conclude about how air temperature affects the speed of sound?
Air temperature has no effect on the speed of sound.
When air temperature increases, the speed of sound decreases.
When air temperature increases, the speed of sound increases.
When air temperature increases, the speed of sound remains the same.
What is the best explanation for why sound travels faster in air at 45 °C than at 0 °C?
Warm air particles have more energy and can vibrate faster
Warm air particles have less energy and vibrate more slowly
Cold air particles have more energy and can vibrate faster
Cold air particles have more energy and vibrate more slowly
A student did an experiment to determine the speed of sound through different substances. The
graph for the experiment is shown.

Why does sound travel slower through gases (air) than through liquids (water) or solids (gold and glass)?
Particles in gases are further apart than particles in liquids and solids.
Particles in gases are closer together than particles in liquids and solids
Gas particles have less energy than particles in liquids and solids
Gas particles transfer energy better than particles in liquids and solids
What would be a reasonable explanation of why sound travels faster through glass than gold?
Gold particles are closer together than glass particles
Glass particles are further apart than gold particles
Glass is gas but gold is solid
Glass transfers energy better than gold.

Why does the school music room have foam panels on the walls?
So everyone can make a lot of noise
to help prevent sounds from going to other parts of the school
because it looks good
to keep the thermal energy from transferring to sounds
When a sound wave hits the eardrum, what happens to the eardrum to allow the transmission of the sound to the inner ear?
it vibrates
it ruptures (breaks)

Why can't humans hear sounds made by animals such as whales?
Humans have a great range of sounds that can be heard.

Whales are too large to make any sounds.
Why would a band want to have each of these different types of saxophones play in a concert?
The music would be louder.
