Sound Waves
This is how sound waves travel through a medium.
vibrating particles/air molecules
This state of matter has a definite shape and volume
What is solid?
This device is used to measure length.
What is a ruler?"
This term describes the change from solid to liquid.
What is melting?
This range represents the typical human hearing frequencies in Hertz.
What is between 20 Hz and 20,000 Hz?
This term describes the highness or lowness of a sound
What is pitch or frequency
"In this state, matter has a definite volume but no fixed shape.
What is liquid?
This scale measures temperature in water boiling at 100 degrees.
What is Celsius?
This is the process where a gas turns directly into a solid.
What is deposition
This term is used to describe unwanted or disruptive sound.
What is noise?
This unit measures the intensity of sound.
What is decibel?
This process turns a solid directly into a gas.
What is sublimation
This unit is used to measure distance in SI.
What is meter.
In this state of matter, particles are tightly packed but can flow around each other.
What is liquid?
In a concert hall, this aspect is crucial for ensuring sound quality for the audience.
What is acoustics?
This event occurs when a sound wave bounces off a surface

This term describes the amount of mass per unit volume
What is density?
This degree in known as the coldest in universe.
what is -273 degrees celcius.
This change of state occurs when a liquid becomes a gas.
What is evaporation?
This property of sound is affected by the medium through which it travels.
What is speed?
This effect is observed when there's a change in frequency due to the movement of a source.
What is the Doppler effect.
Particles in this state of matter move the fastest.
What is gas?
This term describes the amount of matter in an object.
What is mass?
This is the term for a liquid changing into a solid.
What is freezing?
This effect refers to the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source.
What is the Doppler effect?
