At the simplest level, heat conductivity in metals is governed by two processes - the lattice vibrations and the transport of the free electrons. What makes a metal to be good heat conductors in general is predominantly due to these free electrons. So the rate of thermal conductivity depends on how easily they can move and "carry" the heat from one location to another (since the electron gas has very low specific heat, they absorb heat very easily and also gives off heat very easily).
At "high" temperatures (i.e. room temperature and above), the mechanism that dominates the electron transport in metals is the electron-phonon interaction. Phonons are lattice vibrations. The coupling between electrons and phonons in a solid is very complicated and depends on, for example, the phonon spectrum. Thus, this can vary from one material to another, and even in a material, can very in one direction versus another.
For copper, it has a relatively weaker electron-phonon coupling than, let's say, Pb and Al. So at a given temperature, the conduction electrons do not get "interfered" with the phonons as strongly as Pb and Al (or even Fe). So it can move more efficiently.
This is also the reason why Cu is also a better electrical conductor than most other metals at room temperature. Ironically, because of its weak coupling with the phonons, it doesn't have enough "glue" to form the necessary Cooper Pairs at very low temperatures and thus, it does not become a superconductor, whereas poorer conductors like Pb and Nb can, due to the stronger electron-phonon coupling strength.
Copper has more electrons on its outer orbital than aluminum or brass. This way the electrons, which carry the heat, are more free to move around and spread heat. So if a substance has more electrons on its outer orbital then is can conduct heat faster.
Most copper alloys conduct heat better than most aluminum alloys do. That said, you can probably find exceptions: aluminum alloys that conduct heat better than copper alloys.
Yes. Copper is a better conductor than aluminum.
Copper is NOT the best heat conductor, you are misinformed. Silver is a better conductor than copper and diamond is better still, it is 5 times better than copper.
because i like birthday cakes
because cookies r rectangular
Because it does
yes
We know that silver is the best heat conductor among the metals, followed by copper.
Diamond, or metals such as silver and copper.
Conductor, it is actually one of the best conductors for both heat and electricity.
Copper
Materials that are conductors of heat include metal, copper and steel.
We know that silver is the best heat conductor among the metals, followed by copper.
Not exactly. That is why it warms up with heat. A good conductor of heat like copper or iron is best conductor in comparision to water.
NO ! Now the graphens are considered the best heat conductors.
No. Copper is a good conductor of heat.
yes copper is a good conductor of heat only becuase it comes in the conductor of heat
It lets heat go from one end to another.
Diamond, or metals such as silver and copper.
Steel and copper are both metals, but copper is the best conductor.
Conductor, it is actually one of the best conductors for both heat and electricity.
Silver, copper, gold are the best conductors of heat. In this order.
aluminum is the best, then copper then stainless steel
yes copper is actually a very good insulator to both heat and electric conducting A2: NO. Copper is about the second-best electrical conductor, next to silver. It is also a very Good heat conductor. Try heating an iron poker in a fire. The heat travels slowly to the opposite end. A copper wire, however, if stuck in the fire, will transfer heat Very quickly--you won't be able to hold the other end of it! wikipedia.org/copper
