Which metal is best conductor of heat and electricity
Silver MetalAmong the best conductors of heat and electricity is silver.
Silver Metal with a thermal conduction value of approximately 430 w/(mk).
gold and copper both come near to silver respectively, and with copper being considerably less expensive in many applications it is often preferred over the silver..
What are 4 poor conductors
Non-metals are generally bad conductors or insulators. Metals, on the other hand, are good conductors. Some other examples of poor conductors of electricity are mica, paper, wood, glass, rubber, Teflon, etc. Some examples of poor conductors of heat are air, lead, etc.
Is Aluminium a good conductor of heat and electricity
Aluminum is an excellent heat and electricity conductor and in relation to its weight is almost twice as good a conductor as copper. This has made aluminum the first choice for major power transmission lines.

What are 3 types of conductors
Of all the materials, the top three are silver, copper and aluminum. Silver is known to be the best conductor of electricity but it is not widely used for economic reasons. It is only used for special equipment like satellites. Copper, though not as high as silver, also has high conductivity.

Which of the following is conductor of heat and electricity
Copper is a good conductor of heat. This means that if you heat one end of a piece of copper, the other end will quickly reach the same temperature. Most metals are pretty good conductors; however, apart from silver, copper is the best.
What is the good conductor
Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors.
Is Diamond a good conductor of heat and electricity
Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon scattering. Thermal conductivity of natural diamond was measured to be about 2200W/(m·K), which is five times more than silver, the most thermally conductive metal.
Which metal is the poorest conductor of heat and electricity
LeadLead is the poorest conductor of heat as it conducts heat very slowly so it acts as an insulator and used as lead coolant rods in many reactions.
