a form of energy (thermal energy)
Oops!
Okay!
What is radiation?
thermal energy carried through electro magnetic waves

What kind of energy does all matter have?
thermal energy
Oops!
Okay!
What is conduction?
particles with more thermal energy bump into objects with less thermal energy - only in solids
Oops!
Okay!
What is convection?
only in gases and liquids, moves in circles: heat rises and less thermal energy falls creating circles
Oops!
Okay!
What is the law of the conservation of energy?
Energy cannot be created or destroyed only rearranged

Okay!
What does adding energy do to the atoms in matter?
makes them vibrate or move faster

What is it called when multiple atoms bond together? (Ex. H2O)
molecule

Okay!
What is a conductor?
materials that allow heat to travel freely through them (like metal)
Oops!
Okay!
What is an insulator?
things that trap heat easily, and heat does not flow through them easily
Oops!
Okay!
In what direction does thermal energy travel?
hot to cold

Okay!
What happens to matter as the particles or molecules speed up?
it gets warmer
