Question

At absolute zero silver wire behaves as.
A) Superconductor.
B) Semiconductor.
C) Perfect insulator.
D) Semi insulator.

Answer 1

The transfer of energy is done by the vibration of the molecules about their position and the vibration increases or decreases according to the amount of energy the molecules it has at low temperature the energy state of the molecules will be less and at high temperature the energy will be more.

Complete step by step answer:
The molecules in any material are responsible to transfer the energy of the particle from one point to another point in the material. The amount of energy transferred by the material helps us decide that the particle is an insulator or conductor or a semiconductor.
A conductor is a material that is a good conductor of heat and electricity and also it has free electrons in normal conditions the vibration of molecules can simply help the conductor to transfer the heat and electricity from one point to another point.
As the insulator has less molecule vibration in normal conditions, the molecule has very few free electrons on the surface in normal condition and therefore the transfer of heat and electricity is very less.
On the other hand, semiconductors are the materials that have the conduction of electricity more than the insulators and less than the conductors.
At absolute zero temperature the vibration of the molecules will slow down and therefore the silver wire will start behaving as a perfect insulator.

Note:
The lattice vibration in the material is responsible for the transfer of heat energy in the different material whereas the free electrons are responsible for the transfer of electricity in the material so when the absolute zero temperature is reached then the lattice vibration about their position is decreased and due to which the silver wire behaves as an insulator the scientists have practically not reached this situation.
