Graphically represent the variatin of resistivity of carbon with temperture

Explanation

To graphically represent the variation of resistivity of carbon with temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Relationship**: Recognize that the resistivity of carbon decreases as the temperature increases. This is a characteristic behavior of semiconductors and certain materials like carbon.

2. **Set Up the Axes**: Draw a Cartesian coordinate system. Label the vertical axis as "Resistivity (ρ)" and the horizontal axis as "Temperature (T)".
