Energy Transformation
Food contains what kind of potential energy?
Chemical Energy
What wave property determines the loudness of a sound wave?
The amplitude
The range of waves from radio to gamma is called the ______________ _____________ .
The Electromagnetic Spectrum
Hot rises and cold sinks happens in this kind of energy transfer.
Convection
This type of material allows heat and energy to pass through it. Metal is a good one.
Conductor
What energy transformations are taking place?
Walking
Chemical -> kinetic/mechanical
When sound waves pass from air into water, what happens to them?
They speed up
True of False
Microwaves are higher on the electromagnetic spectrum than X-rays
False
This occurs when you put cold ice cream in your mouth.
Conduction
When light passes through a material but bends in the process.
Refraction
An electric car has three major energy transformations. What are they?
Electric --> Chemical ---> Mechanical
The frequency of sound waves determine the _______.
Pitch
When the frequency of a wave increases, what happens to the wavelength?
They get shorter
The total energy of all the particles in something.
Thermal Energy
The sum of the potential energy and the kinetic energy.
Mechanical Energy
In photosynthesis _________________ energy from the sun is transformed into _________________ energy.
Radiant to chemical energy
Sound waves are (Mechanical/Electromagnetic) and (Transverse/Longitudinal).
Mechanical and Longitudinal
What is traveling at a greater speed Microwaves or Gamma Rays?
What is the same speed?
Heat transfer through Electromagnetic Waves.
Radiation
the pitch of a sound can seem to change if its source or listener is in motion.
What is the doppler effect?
What is the law of Energy Conservation?
Energy cannot be created or destroyed. Only changed.
Does sound travel faster through diamond or water?
diamond
These waves carry phone signals.
Microwaves
This is a measure of the average kinetic energy in an object.
Temperature
a wave that moves matter up and down as it travels through a medium.
What is a transverse wave?
