Answer: Increases with increasing temperature.
- A Decreases with increasing temperature
- B Increases with increasing temperature
- C Is independent of temperature
- D Is zero at all temperatures
Correct answer: B. Increases with increasing temperature
Explanation: At higher temperatures, more electrons gain enough energy to jump from the valence band to the conduction band, increasing conductivity.
The three cubic unit cells: Simple Cubic has atoms only at corners; Body-Centred adds one atom at the centre; Face-Centred adds one atom at the centre of each of the 6 faces, giving the highest packing efficiency.
