Why dull black surface heats up more quickly than bright shiny surfaces?
The shinier the object, the more heat will reflect off of it. For example, a black carwill heat up much faster as the dull black will absorb the heat, while a shiny coloured car will reflect the heat molocules off.
Which type of surfaces are poor radiators and absorber of heat?
Shiny metallic surfaces, polished surfaces, and light-colored surfaces are poor radiators and absorbers of heat. These surfaces reflect more heat energy than they absorb, which results in lower heat gain.
Is it true that shiny materials absorb radiant energy?
I believe that shiny surfaces reflect radiant energy.
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.
Does shiny black absorb more sun then dull black?
Yes, shiny black absorbs less sunlight than dull black. Shiny surfaces reflect more light, so less heat is absorbed compared to dull surfaces which absorb more light and heat.
Why does shiny surfaces absorbe more energy then dull surfaces?
Because, shiny surfaces reflect heat, they don't emit much heat and they don't absorb much heat!

Why are shiny outer surfaces needed in a vacuum flask?
The outer surfaces do not need to be shiny. The interior ones do, to reflect heat back rather than let the heat pass out of the vacuum flask. The vacuum between the double walls of the flask also reduces heat loss.

Which surfaces are poor radaitors and absorbers of heat?
Shiny and reflective surfaces like polished metals are poor radiators and absorbers of heat. This is because they reflect most of the incoming radiation rather than absorbing it. Absorption and emission of heat are higher in rough, dark, or matte surfaces compared to shiny ones.
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 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.
How can you prevent heat loss by using air gaps insulation and shiny surfaces?
Air gaps can trap pockets of still air, which is a poor conductor of heat, reducing heat transfer. Shiny surfaces can reflect heat radiation, reducing heat loss. By combining these two insulation techniques, you can effectively prevent heat loss in a space.
What type of surface reflect heat?
light and smooth surfaces reflect heat energy
