helium
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
yes copper is a good conductor of heat only becuase it comes in the conductor of heat
No, benzene is a poor conductor of heat as it is a nonpolar molecule. This means that it does not have free-moving electrons that can efficiently transfer heat energy.
Gold is a good conductor of electricity but a poor conductor of heat. This is due to its high electrical conductivity resulting from its high electron mobility. However, gold's ability to conduct heat is lower compared to other metals like copper or aluminum due to its high density and low specific heat capacity.
Yes, because it makes up 80% of the air, and air conducts heat.
Vacuum
Glass
The poorest conductor of electricity is typically rubber or glass, as they have very high resistance. The best conductor of electricity is silver, followed by copper, due to their low resistance properties.
The poorest conductor of heat is typically materials with low thermal conductivity, such as wood, plastic, or glass. These materials do not conduct heat as efficiently as metals like copper or aluminum.
not gold
The poorest conductor of electricity among the options listed is lead. Lead has low electrical conductivity compared to tin, zinc, and aluminum.
air
Pencil lead is the poorest electrical conductor among the materials listed. While steel and glass are poor conductors, aluminum is a relatively good conductor of electricity.
Lead is a poor conductor of heat because it has a low thermal conductivity due to its atomic structure. Lead atoms are arranged in a way that does not allow for efficient transfer of heat energy through the material. Additionally, lead has a relatively high density and atomic mass, which further hinder the movement of heat within the material.
It is not a heat conductor.
because it is a heat conductor!
Most of the metals are good conductors of heat and electricity. Exception to this rule is silver and copper. Spoons made out of silver and copper pans used in cooking does not conduct heat easily.
