Is cold metal a better conductor of electricity than warm metal?

In hot metals the kinetic energy of electrons becomes higher and they move randomly so their movement in one direction becomes decreased so the conductance becomes decreased.

∙ 13y agoAll metals have resistance. Resistance depends linearly on temperature: higher temperature higher resistance (close to room temperatures), as temperature gets higher dependence of resistance from temperature becomes more complicated and not linear.

∙ 11y agoMetal is a good conductor because the molecules inside metal are closely packed together. When heat is passed through the metal (the process of conduction) the molecules are so tightly passed that the heat moves through the metal quickly.

∙ 13y agoYes ! Cold medal is a great conductor !
For metals the electrical conductivity decrease when the temperature is increasing.

What metals insulate electricity?
Metals actually conduct electricity, not insulate them. Some metals conduct better than others, but the point is that metals don't insulate heat or electricity at all.Glucose rubber cold glass and water
Why metal faster heat transfer than plastic?
I understand that this is for the same reason that a metal transfers electricity better: this is a result of a large number of free electrons, that is, electrons that are relatively free to move around.
Is sand a conductor for electricity?
Depends what the sand is made of and what is in it. Pure silica sand that is try is a poor conductor. If the sand has lots of ferro-magnesium minerals the conductiveity increased. Add salty water and even more conductivity. Things that are conductive contain metals. Sodium is a metal. So sodium chloride dissolved in water is also a good conductor
Why is aluminium a good conductor of heat?
it keeps heat in & reflects light
Why does a metal spoon get hot in a pot of boiling water?
'nothing, it's like putting a spoon in a hot soup' Wrong ^ As the metal spoon is a better conductor of heat than the air the hot water (or soup) and the spoon as a larger surface area with the air (or active sight) it transfers heat to the surrounding faster, thus cooling the hot liquid faster.
Aluminum foil is it a cold conductor?
Things do not conduct cold, they conduct heat. Being a metal aluminum foil is both a good conductor of heat and electricity.
Is cold water best conductor of electricity?
No, but impure is a good conductor of electricity.
Is cold water a better conductor than hot?

Is a silver spoon better conductor than a balloon filled with helium?
A very good conductor.
Is a rubber eraser a conductor or a Insulator?
a pencil eraser is a conductor .
What material is the better conductor of heat cold stainless steel ceramic or plastic?
The better conductor is stainless steel.
Why does a sethoscope feel cold?
is it a stethoscope? if it is, then my answer is correct. they don't feel cold. they check your heartbeat from different directions. the end works as a speaker. it has a tiny hole which collects sound and the ear plugs emphasize it because metal is not only a good conductor of electricity, but also a good conductor of sound waves.
Which conducts electricity better a hot piece of steel or a cold piece of steel?
The electrical conductivity of a metal generally decreases with increasing temperature. Inversely, the electrical conductivity of a semi-conductor increases with increasing temperature.Source: UK GCSE (high school) science education.
What metals insulate electricity?
Metals actually conduct electricity, not insulate them. Some metals conduct better than others, but the point is that metals don't insulate heat or electricity at all.Glucose rubber cold glass and water
Why does electricity flows through cold metals easily?
Because the molecules in metal are slower when cold and therefore let electricity run through it easier.
Why don't wooden spoons get cold but metal spoons do?
Because wood is a poor conductor of heat.
Materials which lets electricity go through them are called?
Conductor are materials that conduct electricity. There are also semiconductors, which conduct electricity but not as well, and superconductors, which conduct electricity without resistance when very cold.
