All metals transfer heat energy at the same rate?

No, (nearly) all metals have different thermal conductivity, since they all have different atomic/molecular structures.


Why do you usually choose copper for wires and not other metals?

Copper is used because of its higher conductivity. Although silver has more conductivity then copper but it is not used because of its cost, however silver is used in some specialized equipments such as satellites. Copper or any other metals conductivity properties is based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.


What properties do alluminum and copper share?

Aluminum (Al) and Copper (Cu) are metals, and all metals share the same properties: Malleable (can be flattened or shaped) Heat and Electric conductivity Luster (shine) and Density (higher than non-metals) Aluminum (Al) and Copper (Cu) are metals, and all metals share the same properties: Malleable (can be flattened or shaped) Heat and Electric conductivity Luster (shine) and Density (higher than non-metals)


Is magnesium an electrical conductivity?

All metals are electrically conductive.


Does potassium have thermal or electricity conductivity?

Like all metals, it conducts heat and electricity.


What metals do not conduct electicity?

All do - some just have greater conductivity than others


Are alkali metals thermal or electrical conductivity?

The alkali metals are the most reactive metals in the periodic table of elements.


What metals have thermal conductivity?

ALL metals are pretty good conductors of heat. Some, like gold, are very good conductors of heat.


One property of most nonmetals is that they are what?

High ionization energy and poor electrical conductivity


Is the electrical conductivity of molten metals high or low?

Metals are already good electrical conductors, and melting metals increases their electrical conductivity. All that heat (thermal energy) allows electrons a lot more mobility so they can more effectively contribute to current flow.


A what is a material through which energy can be easily transferred as heat?

Any material which has high thermal conductivity can easily transfer energy as heat. As far as I know, all metals have high thermal conductivity. Copper, gold and silver especially have high thermal conductivity. Diamond and graphene have VERY high thermal conductivity, so this is not restricted to only metals.


Why does copper conduct heat faster then steel or brass?

Copper's conductivity properties are based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.
