Why conductivity of conductor decreases while of semiconductor increases with increasing temperature?

Explanation

To understand why the conductivity of a conductor decreases while that of a semiconductor increases with increasing temperature, we can break down the explanation into a series of logical steps:

### Step 1: Understanding Conductivity
Conductivity (\( \sigma \)) in materials is influenced by two main factors:
1. The number of charge carriers (electrons) available for conduction.
2. The frequency of collisions between these charge carriers and the lattice atoms of the material.

### Step 2: Conductivity in Conductors
