Show variation of resistivity of copper as a function of temperature in a graph.

Explanation

To show the variation of resistivity of copper as a function of temperature, we can follow these steps:

### Step 1: Understand the relationship between resistivity and temperature
Resistivity (\( \rho \)) of a conductor like copper increases with temperature. The relationship can be expressed as:
\[ \rho(T) = \rho_0 (1 + \alpha (T - T_0)) \]
where:
