    Why does the conductivity of a semi conductor change with the rise in temperature ?

    Answer) When a semi conductor is heated more & more electrons get enough energy to jump across the forbidden energy gap from valence band to the conduction band, where they are free to conduct electricity. Thereby increasing the conductivity of a semi conductor.
