What are the best absorbers of thermal radiation?
Black, dull surfaces are the best absorbers of thermal radiation because the heat doesn't reflect off it unlike shiny surfaces.
The surfaces of a dewar flask are silvered for the purpose of minimizing heat transfer by what process?
Radiation
What type of surfaces are good radiators of heat?
Dull black surfaces they are also best at absorbing it as well. [Shiny and silvery or white surfaces are poor radiators and absorbers of heat. However they are very good in reflecting heat radiation.]
What surfaces are better absorbers and emitters of thermal radiation?
Dark matt surfaces absorb heat radiation falling on them much better than bright glossy surfaces, such as gloss white or silver. They also emit much more heat radiation (at any given temp.)
What surfaces are slow to emit infrared radiation?
Glass, Chrome

Why do white surfaces stay cooler than dark ones?
White surfaces reflect infrared radiation (which includes light and heat), while darker/blacker surfaces absorbinfrared radiation. As a result, lighter/whiter surfaces will be cooler because they reflect heat, and darker/blacker surfaces will be warmer because they absorb heat. The amount by which a surface reflects (or absorbs) infrared radiation is referred to as albedo and is usually expressed as a value between 0 (no reflection) and 1 (perfect reflection).
Which emits the most infra red radiation matte silver surface or shiny black surface?
Matte (dull) and black surfaces emit infrared radiation at a faster rate than shiny and white surfaces.
What surfaces are slow to emit infrared radiation?
Glass, Chrome
Which surfaces are poor radaitors and absorbers of heat?
fu
What are the best absorbers of heat surfaces?
smooth, dark colored
Is a good absorber of radiation a good emitter or a poor emitter?
It is a good emitter, as you can not have a good absorber, which isn't a good emitter. Dark, Matt surfaces are good emitters and absorbers e.g. a saucepan.
The best absorbers of heat are blank surfaces?
That's a dum Question , but it's black,blank,surfaces(usually)
The best absorbers of heat are what kinds of surfaces?
Black surfaces with large area absorb heat best (a powder for example that is black).
