A metal. It's a better conductor than liquid, gas, or rubber.
The most common one that is very effective is METAL. Well, metal is not an element Of elements, silver is the best conductor of heat followed by copper. The best conductor of heat overall at room temperature is diamond, not an element of course.
Steel and copper are both metals, but copper is the best conductor.
No metal is semiconductor. By definition metal is conductor. There are metalloids elements. Like silicon and germanium. They are semiconductors. There is no hard and fast definition of such elements.
Metal is a conductor and the electricity will easily flow through it.
the metal that serves as the best conductor of electric charge is the METAL
Silver is the best conductor
Metal
Silver is the best conductor out of the two.
Silver is the best conductor there is, no matter what it is made into.
Metals are indeed good conductors. Silver, which is a metal, is the best conductor.
Silver is the second best conductor of electricity after copper.
copper
Silver is.
Silver or Argentum (Ag)The best conductor of heat and electricity is silver.
It is made of metal because metal is the best conductor of heat.
Gold is the best heat conductor in the world.
