Transcript of Energy-

Thermal Conductor - a material that is good at conducting heat (ex. metals)
Insulator - a material that is poor at conducting heat (ex. wood, air)
Forms of Energy
1. mechanical energy- energy of movement
2. chemical energy - energy stored in the bonds of
compounds
3. electrical energy - energy of moving
electrons
Temperature
-a measure of the average kinetic energy (motion of the molecules) of a substance
Energy Conversion
The process in which one
kind of energy changes into another.
Heat always moves from hot
(fast moving particles) to
cold
(slow moving particles).
Energy
A question:
Could a block of ice have more thermal energy than a pot of water?
Energy isn't lost, it is conserved
(neither created nor destroyed).
Energy-
the ability to move or change matter
Thermal energy -
-the total kinetic energy of a substance
Kinetic energy - moving energy
Potential energy - energy that is stored in an object
4. Thermal Energy (heat energy) - energy of moving atoms
Others: Sound, electromagnetic, nuclear energy
Yes! The block of ice could have more thermal energy if the block of ice had a much greater mass than the mass of the boiling water
