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.]
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).
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.
Who emits more radiation a white body or a black body?
Good absorbers of radiation are also effective emitters. Thus, a black body, which more readily absorbs infrared radiation also emits it more readily.
Why black bodies are good absorbers of heat?
the color black is a good conductor of heat, so black bodies are good absorbers of heat

Are good absorbers good emitters as to do with black collector of solar heaters?

Which surfaces are the best emitters of heat?
black dull surfaces but im looking for why these surfaces are the worst?
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).
The best absorbers of heat are blank surfaces?
That's a dum Question , but it's black,blank,surfaces(usually)
Why does a firefighter wear a silver suit instead of a black suit?
Sliver surfaces reflect heat keeping the body of the firefighter cool, whereas black surfaces are good absorbers of heat.
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.
Who emits more radiation a white body or a black body?

Why black bodies are good absorbers of heat?
the color black is a good conductor of heat, so black bodies are good absorbers of heat
Is dull black surface is a good radiator of heat?
Yes, it is. As dull and black surfaces are the best emitters as well as the best absorbers of radiation. Hope my answer is good enough to be stand up your question needs.
Do all objects equally conduct absorb emit heat?
The emitting and absorbtion of heat is related to ' thermal radiation', whereas the 'conduction' of heat is a separate topic in physics. Firstly, thermal radiation is not equivalent across all substances. Darker coloured 'objects' such as those with a 'matt black' colour are the best emitters and absorbers of 'heat'. Lighter silvered 'objects' are the poorest emitters, the poorest absorbers, and the best reflectors of heat. Similarly, not all objects equally conduct heat. Metals are the best conductors of heat; and so non-metals are the worst. All Insulators do not conduct heat. Examples of good insulators are: plastic and wood.
What is the difference between the way black and white surfaces affect light?
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.
