∙ 9y agoThe rough surfaces are good emitters of heat because of the number of atoms. The atoms and electrons are closely packed therefore making it a good emitter of heat.

Is a good reflector of radiation a good emitter of radiation?
A good absorber of radiation is a good emitter. Radiation is the energy that that comes from a source and travels through space or through something. Some examples of radiation include light, heat and sound.
Is a good emitter of heat also a good reflector of heat?
Yes..
What types of surfaces absorb heat?
Dark, rough, and/or porous surfaces absorb the most heat (ex. Asphalt)
What produces more heat rough surface and a smooth or surface two smooth surfaces or two rough surfaces or two surfaces with oil between them?
two rough ones - there will be more friction xx
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 do rough surfaces absorb and radiate heat fast?
Due to their greater surface area.
Why does a black colour absorb more heat?
because its a good emitter/absorber of radiation
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.
Why dark surface is a good emitters of heat?
The dark surfaces heat up faster because dark surfaces attract sunlight faster than light surfaces.
Which surfaces absorb heat?
All surfaces absorb some heat.
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.
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.
