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.

The best material is copper of alumninium.
A substance becomes cold by radiating its heat out to its surrounding.
The greenhouse effect (greenhouse gases capture heat radiating up from the earth).
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.
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.
Dark surfaces are the best.
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.
The best metal for conducting heat is silver.
Gold is the best heat conductor in the world.

Radiation - electromagnetic, thus no material need be in contact with the radiating object. Conduction : heat conducted by direct contact. Convection : heat is 'conducted' to a transfer material (fluid) which then caries it away by gravity (changes in density).
Silver or Argentum (Ag)The best conductor of heat and electricity is silver.
an insulator- to prevent or reduce the transfer of electricity,heat,or sound by surrounding or lining with a non-conducting material.
