Silver is about the best for conduction, with copper not far behind. For radiation, a black body is best, and will radiate more heat the hotter it is. The sun for instance acts as a black body with temperature about 6000 deg C.

Copper, silver, and aluminum are considered some of the best heat conducting metals due to their high thermal conductivity properties. These metals are commonly used in heat sinks, electric wiring, and cooking utensils where efficient heat transfer is important.
The U value of a material or building component can be determined by conducting a thermal conductivity test, which measures how well the material conducts heat. This value helps assess the material's insulation properties and its ability to resist heat flow.
Materials with high thermal conductivity, such as metals like copper or aluminum, are good for absorbing heat from air. They can quickly transfer the heat to a heat sink or storage medium for redistribution or use. Additionally, materials with high specific heat capacity, like water or oils, can also effectively absorb heat from air over a longer period of time.

Dark surfaces are the best.
Copper is one of the best materials for conducting heat due to its high thermal conductivity. Other good heat conductors include aluminum and silver. These materials are commonly used in cookware and electronic components to efficiently transfer heat.
Heat promoting mechanism include exothermic reactions and the radiating of heat through conductance. Exothermic reactions include the combustion of carbon based fuels which release heat. The radiating of heat can come from electronic space heater that release warmth through their conducting metal filaments.
Gold is the best heat conductor in the world.
NO! Ideal materials for radiating heat are black. If a body is radiating lots of heat then its electromagnetic(EM) spectrum should peak below the visible range(Infrared region),making the material look dark.

When thermal conductivity is higher, it means that the material is better at conducting heat. This means that heat transfers more easily through the material, making it a better conductor of heat compared to a material with lower thermal conductivity.
Depends on how you read the question. If the heat is "going away" somewhere, then the heat must be conducting, convecting or radiating away. Or if you are supplying heat to something that would otherwise be cooling down, it goes into maintaining the molecular/atomic vibrations of the material.

an insulator- to prevent or reduce the transfer of electricity,heat,or sound by surrounding or lining with a non-conducting material.
