At what temperature range most of the metals becomes superconductors

Explanation

To determine the temperature range at which most metals become superconductors, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Superconductivity**: Superconductivity is a phenomenon where a material exhibits zero electrical resistance and expulsion of magnetic fields when cooled below a certain temperature.

2. **Temperature and Resistivity**: As temperature increases, the resistivity of metals also increases. This is because the particles in the metal move faster at higher temperatures, leading to more collisions and thus higher resistance to the flow of electric current.
