Kinetic energy
energy of motion, faster = more
Potential energy
stored energy of position, higher =more
Electromagnetic energy
energy which travels through space & water
Energy absorbed
energy is “soaked” in at surface, temp goes up
Energy radiated
energy which was absorbed is given off, temp goes down
Energy reflected
energy “bounces off” the surface without being absorbed, temp stays the same
Good absorber
dark, dull, & rough
Albedo
the reflected energy from a surface
Good reflector
light, shiny, smooth
Specific heat
physical property, shows how quickly a substance will change temp
Low specific heat
heats & cools quickly
High specific heat
heats & cools slowly
Highest specific heat
liquid water, changes slowly
Convection
heat flow in a solid by collisions of molecules
Heat source
high energy
Heat sink
low energy
Heat flows from
source to a sink
Closed energy system
no heat is “lost”
Convection
heat flow of a liquid or gas caused by a difference in density
Hot(less dense)
rises
Cold(more dense)
sinks
