heat transfer and energy interactions Flashcards
(14 cards)
how can heat transferred be moved or transferred
throughout the atmosphere
convection
heat transfers though fluid (gas and liquids) .Is the driving force behind weather
how does convection work?
top (less dense, light, expands and rises)
bottom (more dense, heavy, contracts and sinks)
what forms from convection
clouds, hot air balloons, etc form by convection
conduction
heat transfer from solids
how does conduction work?
energy is passed through the atomic collisions to molecular contact
radiation
energy travels though space in the form of electromagnetic spectrum
refract
waves pass through
scatter
travel in all directions
absorb
waves are taken in by a surface on earth
a good absorber…
is a good radiator
characteristics of absorb
dark in color, rough in surface, dull (black tops)
reflect
waves redirected
