Heat Transfer
What is a change in state
Changing forms (Solid, liquid, Gas)
True or False
The amount of kinetic and potential energy in a closed system should always add up to the same amount of total energy
True
True or False:
All waves travel at the same speed
False
What happens when a material absorbs waves
The material takes in light energy
Which one has more energy:
Increasing frequency or increasing wavelength
Increasing Frequency
What is thermal equalirium
When heat transfer stops because they reach the same temperature
When a rollar coaster is at the bottom of the coaster, which type of energy is the highest
What happens to sound waves as they travel through more dense material
They speed up
What happens to a wave when it is reflected
It bounces off of an object
Which of the following waves have the longest wavelength?
Ultraviolet, x-Ray, Infrared, visible
Infrared
Heat always moves in which direction?
From Hot to Cold
What is the Law of Conservation of Energy
Energy cannot be created or destroyed only transferred and transformed
What happens to light waves as they travel through more dense material
They slow down
A pencil appearing bent because the light wave slowed down in liquid is an example of which wave behavior
Refraction
What part of the spectrum can humans see
Visible light
Which type of heat transfer is through electromagnetic waves
Radiation
Friction causes kinetic energy to transform into what type of energy
Thermal energy
Sound Waves
The light waves going through the window is an example of ___________
Transmission
Which wave is the smallest part of the specrum
Visible light
Which type of heat transfer to neighboring particles (Particles directly touching)
Conduction
What is the difference betweeen energy transfer and energy transformation?
Energy Transfer- from one object or medium to another
Energy Transformation- from one type of energy to another
Give an example of a transverse wave and a longitudinal wave
Transverse: Light
Longitudinal: Sound
Reflected
