That sounds like the description of a metal.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
That really depends on the material. Many forks are made out of metal. When they are shiny, they are most likely out of metal. In that case, they are good conductors of both heat and electricity. If they are made out of plastic, they are not good conductors.
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.
Insulators are conductors
Conductors have a (low) Electrical resistance.
conductors are generally are made of metals and naturally metals are of shiny and so u can tell that all conductors of heat shiny
Conductors of heat, malleable,shiny
metals are shiny and good conductors of heat and electricity. Nonmetals are dull and poor conductors of heat and electricity.
Metals. The elements that are classified as "Transition Metals" and are located in Groups 3 - 12 of the Periodic Table are elements that are shiny bendable and good conductors of electricity.
Many - but not all - are poor conductors of electric current.
metals
Metals are generally very good conductors of heat and electricity, hard, shiny, malleable, ductile, and solid at room temperature. Some are magnetic.
Alkali Earth metals are shiny. All metals have a property called luster witch means that they are shiny. All metals are also malleable, ductile, and are good conductors.
They are shiny, malleable, they have high melting and boiling points, and they are good conductors of heat and electricity.
Generally speaking, materials that are good conductors of heat are good conductors of electricity. But there is a notable exception. Diamond, an allotrope of carbon, conducts heat better than any metal, but it is an electrical insulator.
