What will be the behavior of conductor at absolute 0 temperature?
Misha Kuznetsov said:It will become a superconducting material and will lose absolutely all of its electrical resistance, among other things.

Misha Kuznetsov said:I didn't say that it's a superconductor because it has zero resistance, I said that a superconducting material loses all of its electrical resistance. Is that incorrect? I meant that some conductors become superconducting at temperatures higher than absolute zero, so at absolute zero they would still be superconducting(is that correct?). Are you saying that I am incorrect because the way I said it, it implied that all conductors can become superconducting? I was referring to the conductors that do become superconducting because I assumed that was what the question was about, was it not? Are you saying that in a superconductor, some electrical resistivity will always be present because of residual resistivity?

ZapperZ said:However, also note that all REAL conductors that do not exhibit superconductivity actually DO NOT get to zero resistance as the temperature approaches 0K
Misha Kuznetsov said:I'm well aware that you know far more than me on this subject, but I said that zero electrical resistivity was caused by becoming superconducting. Not becoming superconducting because it conducts electricity perfectly. I also said, "among other things," notifying that there are other properties of a superconductor. I only mentioned the one about electrical resistivity because it was the main one that came to mind.
I assumed that was what he/she was asking about, and I don't know about what would happen if it was a conductor that couldn't become superconducting, so I didn't say anything about that.
Out of curiosity, what would happen to, for example, copper at zero K?
At absolute zero temperature, the atoms in a conductor stop vibrating and lose all their thermal energy. This leads to a complete absence of resistance, allowing electrical current to flow without any hindrance.
No, it is not possible to reach absolute zero temperature as it is the lowest possible temperature in the universe. The third law of thermodynamics states that it is impossible to reduce the temperature of a system to absolute zero through a finite number of processes.
As a conductor approaches absolute zero temperature, its resistance decreases exponentially. This is due to the decrease in thermal vibrations of the atoms, resulting in a more orderly flow of electrons and less energy loss.
Yes, at absolute zero temperature, a superconductor exhibits perfect conductivity due to the absence of any resistance. This phenomenon is known as zero resistance or superconductivity and is a key property of superconductors.
The study of conductor behavior at absolute zero temperature has numerous applications, including the development of superconductors for use in magnetic levitation trains, high-speed electronic devices, and MRI machines. It also helps in understanding the fundamental principles of thermodynamics and quantum mechanics.
