Question

state and explain the concept of superconductivity

Answer 1

flow of current without energy loss or with zero resistance. The electrical resistance of metals falls with temperature. In some metals, at temperatures close to absolute zero, a critical temperature exists below which the metal becomes superconductive: resistance falls to zero.

Answer 2

$\huge\boxed{SOLUTION}$

The property / phenomenon of infinite conductivity in materials is called superconductivity.

Further Explanation

The temperature at which metals change is the normal operating state for the subconducting state, called the critical temperature / transition temperature. An example of superconductors is Mercury.

It becomes a superconductor at 4k. In the superconducting state the material expels the magnetic field.
