Heat Radiation Flashcards
Heat energy can be transferred by:
- radiation
- conduction
- convection
Heat radiation is
the transfer of heat energy by infrared radiation
Conduction and Convection are
the transfer of energy by particles
Conduction is the main form of heat transfer in…
solids
Convection is the main form of heat transfer in…
liquids and gass
Infrared radiation can be emitted in…
Solids, liquids and gases
The bigger the temperature difference between a body and its surroundings…
the faster energy is transferred by heating
An object that is hotter than its surroundings,
emits more radiation than it absorbs as it cools down
An object that is colder than its surroundings,
emits less radiation than it absorbs as it heats up
What kind of surface absorbs/emits infrared radiation the best?
Dark, matt surfaces
What do light shiny surfaces do to radiation
reflect it
