its simple the things when placed in light shine or glitter like steel,polished metals etc. are shiny things and the things that don't glitter even in light like wood and non metals are dull substances.

Is cotton shiny or a dull fabric?
Shiny
Would you expect a dull or shiny surface to be a better absorber?
Dull surface is a better absorber. A shiny surface would better reflect than absorb.
Which is the best absorber of inferared radiation heat a dull surface or a shiny one?
A dull surface will absorb infrared best, but it needs to be dull at infrared wavelengths. Do not judge the infrared behavior by the visible performance.
Why does dull dark objects emit more heat than bright shiny ones?
Dark objects absorb heat, while bright shiny ones reflect heat back.
Do dull silver surfaces emit the same amount of radiation as shiny white surfaces?
Dull silver surfaces and shiny white surfaces can have different emissivity values, which means they might not emit the same amount of thermal radiation. Emissivity is a property that quantifies how effectively an object emits thermal radiation compared to a perfect blackbody at the same temperature. A blackbody has an emissivity of 1, and objects with emissivity closer to 1 are better emitters of thermal radiation. Dull surfaces, including dull silver surfaces, typically have higher emissivity compared to shiny surfaces. Shiny surfaces often have lower emissivity because their smooth and reflective nature reduces their ability to emit thermal radiation effectively. White surfaces can vary in terms of their shininess and emissivity. A shiny white surface might have a lower emissivity, while a more matte or dull white surface may have a higher emissivity. Therefore, if the dull silver surface has a higher emissivity compared to the shiny white surface, it will emit more thermal radiation than the shiny white surface at the same temperature. However, it's important to note that the exact emissivity values can vary based on the specific properties and conditions of the surfaces, so it's best to refer to specific emissivity measurements for accurate comparisons.

Dull or shiny things warm up faster in the sun?
Shiny because the shiny particles are attracted to the sun particles. Happy! :)
