Types of Energy
Energy from the sun.
Solar energy
Transfer of energy through direct contact is called?
Measure of how hot or cold something is?
Temperature
An object that blocks heat transfer. This means that it is designed to keep heat in OR out.
Insulator
The path through which electricity flows.
Circuits
Energy stored in stretched or compressed object.
Potential energy
Transfer of energy by movement of fluids (liquids/gases).
Convection
Energy that flow from hotter to cooler objects.
Heat
Warm air rises and cool air sinks inside a room.
Convection
An object that moves/transfers heat easily.
Conductor
What type of energy comes from moving objects?
Kinetic energy
Transfer of energy through waves without matter.
Radiation
When materials expand due to heat is called?
Thermal expansion
Heat always moves from HOT to COLD. TRUE or FALSE?
TRUE
A device that stores chemical energy and converts it to electrical energy.
Battery
Energy due to an object’s motion or position.
Energy changing from one form to another is called?
Energy transformations
Materials contracting when cooled is?
Thermal contraction
Coins are usually made of metals like copper or nickel, which conduct electricity. TRUE or FALSE?
TRUE
It is caused by the movement of electrons, and is easily transported through power lines and converted into other forms of energy.
Electrical energy
Energy stored in chemical bonds.
Chemical energy
Law stating energy cannot be created or destroyed?
Law of Conservation of Energy
Device used to measure temperature.
Thermometer
A metal rod is heated on one end, and over time the heat travels to the cooler end even though the rod is not moving. Identify the type of heat transfer taking place.
Conduction
The flow of electrons provides that can be used to do work.
Electrical current
