Energy Transformations
Burning a candle.
Chemical energy -> thermal energy or light energy
Name one way you can reduce heat escaping your home.
Insulation.
When heat is transferred through direct contact of objects
Conduction
Using a hot plate to boil water.
Electrical energy -> thermal energy
Is metal a good conductor of heat or a good insulator?
Good conductor.
When heat is transferred through electromagnetic waves
Radiation

Chemical energy -> mechanical energy
Is plastic a good conductor of heat or a good insulator?
Good insulator.
This type of energy is generated by using using both potential and kinetic energy
Mechanical energy.
When heat is transferred through the movement of particles
Convection
Using a solar-powered calculator.
Light energy -> electrical energy
Name one way you can conserve energy in your home.
Energy efficient appliances, etc.
A person running down the sidewalk has this type of energy.
(Mechanical) kinetic energy.
This type of heat transfer occurs in the mantle of the earth to heat up the molten rock
Convection
A solar panel on the roof of a building used to heat and cool the building.
Light energy -> electrical energy
Name one way to prevent the heat from the sun from entering your house on a hot, summer day.
