Thermal Energy
How much the particles move is?
Thermal Energy
a form of energy that is made of vibrating magnetic and electric fields which travel out from its source as light waves
Light
The ability of material or matter to transfer thermal energy
Thermal Conductivity
How hot or cold matter is
Temperature
the ability to do work or cause change
Energy
conduction, convection, and radiation
3 main ways that thermal energy moves
The change in direction of waves
1) Reflection
2) Refraction
3) Dispersion
Reflection
materials that allow heat to pass through them easily
1) good conductor of heat - metal
2) poor conductor of heat - plastic
Good Conductor of Heat
What is made up of tiny particles?
Matter
What are the 7 forms of energy?
*Look in your packet if needed
kinetic, potential, thermal, chemical, electrical, light, sound
The movement of heat within an object
1) Conduction
2)Convection
3)Radiation
Conduction
The change in speed causes the waves to change direction. This change in speed and direction is called refraction.
1) Reflection
2) Refraction
3) Dispersion
Refraction
materials that do not allow heat to pass through them easily
1) good conductor of heat - metal
2) poor conductor of heat - plastic
Poor Conductor of Heat
Dark area that forms when an object blocks light
1) Shadow
2) Reflection
3) I dont know
Shadow
the energy of movement
1) Kinetic Energy
2) Thermal Energy
3) Potential Energy
Kinetic Energy
movement of thermal energy. Hot parts of the fluid rising and the cooler parts of the fluid sinking.
1) Conduction
2)Convection
3)Radiation
Convection
The change in speed causes the waves to change direction. This change in speed and direction is called refraction.
1) Reflection
2) Refraction
3) Dispersion
Dispersion
What states of matter are better conductors of heat?
1) liquid>gas>solid
2) solid>liquid>gas
3) gas>solid>liquid
Solid>liquid>gas
the measure of how quickly a wave repeats in a given amount of time
1)Wavelength
2)Frequency
3)Time
Frequency
Can have energy due to its positions or structure
1) Kinetic Energy
2) Thermal Energy
3) Potential Energy
Potential Energy
the transfer of energy through electromagnetic waves
1) Conduction
2)Convection
3)Radiation
Radiation
What are the different types of rays and how do you describe them?
*Look in your packet if needed
Incident rays - incoming rays
Reflected rays - bounce off the surface
Examples of good and poor conductors of heat?
Good: Metal Pans
Bad: Plastic
