sun -> nuclear store -> radiation -> earth -> thermal and chemical stores
All objects that are hotter than their surroundings will emit infraredwaves.
Matte, black surfaces are good emitters and good absorbers of thermal radiation.
Silver, shiny (or white) surfaces are poor emitters but are good reflectors of radiation.
Why were the silver and black cover beakers different temperatures?
The beaker with the black cover was cooler because it gave off and absorbed more heat, while the beaker with the silver cover reflected the heat back in.
