energy Flashcards
what’s a mechanical transfer
if there’s force on the object
what’s an electrical transfer
from a charge moving
what’s heat transfer
from energy passing from hot to cold object
what’s radiation transfer
from EM waves
what’s convection
fluid expands and heats
fluid rises
fluid cools and sinks down
convection current formed
“black” properties of radiation
best emitter and absorber
“shiny” properties of radiation
worst emitter
worst absorber
how steam turns a generator
KE of steam
turbine turns
mechanical transfer
to KE store of turbine
transfer to KE store of generator
electrical transfer
