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.]
Why dark surface is a good emitters of heat?
The dark surfaces heat up faster because dark surfaces attract sunlight faster than light surfaces.
Why are rough surfaces good emitter of heat?
A rough surface has more surface area which allows more heat to be transferred.
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 are examples of substances that are a good conductor of transferring energy as heat?
Iron
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!

Which surfaces are the best emitters of heat?
black dull surfaces but im looking for why these surfaces are the worst?
Are good absorbers good emitters as to do with black collector of solar heaters?

How do infrared quartz heaters work?
The infrared quartz heaters have the infrared emitters and they emit infrared rays continuously to heat the heater in the instrument. The heat is generated and infrared emission stops.
