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

In general good absorbers of electromagnetic radiation are also good?
Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.

Are good or poor conductors better emitters?
good conductors are better emitters

Are windows good infrared emitters?
no!

Are silvered surfaces good or poor absorbers of infrared radiation?
Very very poor, they have a tendency of blowing you IP.
Are reflectors or absorbers good for keeping cold?
it's reflectors.....
What are good absorbers of heat?
Good absorbers of heat radiation are like basically materials which are dark in colour. Because for some reason they tend to absorb more radiation than light coloured materials.
