Energy Transformations
Burning a candle. (2 steps)
Chemical energy -> heat energy + light energy
How does heat move?
from hot to cold
Energy that has the ability to fall; this type of energy increases the higher up you go.
Potential (gravitational) energy.
Energy is defined as _________.
The ability to do cause change or do work!
Using a hot plate to boil water. (2 steps)
Electrical energy -> heat energy
What type of heat transfer is demonstrated when a you burn your hand on a heated pot?
conduction
"You can burn it or you can eat it."
Chemical energy.
the direct transfer of heat between objects that are in direct contact with each other.
conduction
The pop can imploded because
of the convection of air from hot to cold.
Energy that moves something from place to place.
Mechanical energy.
Transfer of energy by currents through a liquid or a gas.
Convection
Using a solar-powered calculator. (3 steps)
solar energy -> electrical energy ->light energy
This type of heat transfer allows a campfire to keep you warm.
Radiation
Explain the law of conservation of energy!
Energy cannot be created or destroyed, it can only change forms!
A solar panel on the roof of a building used to heat and cool the building. (2 steps)
solar energy -> electrical energy
Air currents throughout the globe are caused by this type of heat transfer.
Convection
