1.	Assertion: Semiconductors are solids with conductivities in the intermediate range from 10^(-6) -10^4 "ohm"^(-1) m^(-1) Reason : Intermediate conductivityin semiconductor is due to partially filled valence band .
Answer» Assertion and reason both are correct statements and reason is correct explanation for assertion. Assertion and reason both are correct statements but reason is not correct explanation for assertion Assertion is correct statement but reason is wrong statement Assertion is wrong statement but reason is correct statement. SOLUTION :Correct Reason. INTERMEDIATE CONDUCTIVITY of semiconductors is due to small ENERGY gap between FILLED valence band and empty conduction band.
