solar oven Flashcards
Heat travels along a substance from molecule to molecule (between two materials that touch each other)
Conduction
Good conductors
most metals like silver, copper, gold
Poor conductors
(glass, paper, wood, styrofoam)
transfer of energy as it is carried through a liquid or gas
Convection
heat transfer by a circulation of rising warm air (less dense) and sinking cooler air (denser).
“Hot air rises” the more dense air sinks forcing the less dense air upward
Convection
This carries energy from the hot object and causes it to cool down.
the movement of heat in a wave-like motion through an empty space
Radiation
You are doing your homework at a desk that is underneath a lamp. You start to feel hotter because of ___________________from the lamp.
Radiation
You buy a lava lamp from the store. As the lamp heats up, blobs of liquid rise to the top, then sink back down to the bottom. This process continues because of
convection
You are stirring a bowl of hot soup with a metal spoon. The spoon starts to feel warmer because of what kind of heat transfer?
