Are silvered surfaces good or poor absorbers of infrared radiation?
Very very poor, they have a tendency of blowing you IP.
Why dark surfaces are good absorbers of heat and shiny surfaces are poor absorbers of heat?
If you are talking in terms of the suns heat being absorbed by the surfaces then I have the answer. Shiny surfaces naturally deflect the suns rays where as dark surfaces are easy conductors of heat as they naturally catch the suns rays. You will notice with leather or print on a shirt that it gets hot because the rays have nowhere to go. A shiny surface will just deflect it back.
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.]
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.
How does silver coating on surfaces of glass walls minimise heat transfer?
being a poor radiator,the two silver faces reflects heat back and forth and reduce heat by radiation.

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.

Why materials such as plastic foam feather and fur are poor conductors of thermal energy?
Because they trap air, which is a poor conductor of heat. They hold surfaces away from each other, to stop direct conduction.
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 wood a poor heat conductor?
Wood is a poor conductor of heat.
Is it possible to avoid popping your cherry?
Yes: Don't have sex, and don't ride a bike with poor shock absorbers on a rocky road.
Elements that are poor conductors or heat such as bromine?
Silicon is a poor conductor of heat. So is
Is carbon a poor conductor of heat and electricity?
Carbon is a poor conductor of heat and electricity.
