The metal zirconium becomes superconducting at temperatures below 546 mk. calculate the temperature at which zirconium becomes superconducting in degrees celsius. round your answer to 3 decimal places.

-272.604 °C

Explanation:

The metals can conduct electricity, but this conduction has some resistance, and there're dissipations in the energy during the conduction. Some material has the ability, at very low temperatures, to conduce electricity without the resistance. This ability is called superconducting.

The mK corresponds to the miliKevin, and 1 K = 1000 mK, thus, the temperature in Kevin is 0.546 K.

T(K) = T(°C) + 273.15

T(°C) = T(K) - 273.15

T(°C) = 0.546 - 273.15

T(°C) = -272.604 °C

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
