Answer:
Explanation:
Semi conductors are 14th group elements in Periodic table with 4 valance electrons.
As the 4 free electrons available tend to form covalent bond (sharing electrons by nearby atoms), electrons will not be free so as to be available for conduction at low Temperature like 0 Kelvin
HENCE IT BEHAVES LIKE INSULATOR AT LOW TEMPERATURE “with very high resistance”

Answer:
It decreases with increase in temperature
Explanation:
As temp increases more electrons go from valence band to conduction band. So as no of electrons increase resistivitt decreases
