heat moves from warmer to cooler objects

kinetic energy of a substance's atoms; more heat- more movement

how hot or cold; average kinetic energy

potential to kinetic with objects

plugged in/batteries

electromagnetic waves

heat transfer by touch

heat transfer in a liquid

heat transfers by waves in space

gets hotter = larger

gets colder = smaller

helps electricity or heat flow

blocks heat or electricity from flowing

energy of light is transferred to another surface

light goes through transparent objects

light bounces back perfectly

reflecting light in all directions

light bends

perpendicular- electromagnetic waves

range of all radiation

shortest wave/ highest energy: nuclear explosions

helps you see bones 

causes sunburns

ROYGBIV- what we see

imaging of heat; remote controls

radiation that can cook food

longest waves/lowest energy; radio
