Solar Energy
Energy given off by the sun
Conduction
How thermal energy moves from a stove to a pot *This is also how I get burned
Energy
The ability to cause a change
How thermal energy moves
Conduction, Convection, and Radiation
Heat
The movement of thermal energy from one kind of matter to another
Kinetic Energy
Energy of Motion
Convection
When warm matter moves from one place to another * Liquid or Gas Heat rises
Bundles of energy that carry heat
Fuel
Any material that can burn
Waste Heat
Unneeded and unused thermal energy *** Candles and light bulbs are used for light but make heat that is wasted
Temperature
A measure of the average energy of motion of the particles in matter
Thermal Energy
The kinetic energy of particles in matter *We feel it as heat
Bundles of energy that move through matter and empty space *Sunburn
What is Thermal Energy?
The energy of the motion of particles in matter
How is Thermal Energy measured?
Temperature is a measure of the energy of motion in matter
What happens when Thermal Energy is added to matter?
Particles move faster
What happens when Thermal Energ is taken away?
Particles slow down
The process of transferring Thermal Energy is call what?
Heat
What are three ways Thermal Energy can be transferred?
1.Conduction-Happens when particles bump into each other.
2. Convection- Warm matter moves from one place to another.
3. Radiation- When thermal Energy moves through emply space
How is Thermal Energy produced?
1. Burning
2. Solar Energy
How is Thermal Energy is used?
1. Cooking
2. Warm Homes
3. Generate Electricity
