Single Choice
Among the following which statement is incorrect?
ADensity of crystals remains unaffected due to Frenkel defect
BIn BCC unit cell the void space is 32%
CDensity of crystals decreases due to Schottky defect
DElectrical conductivity of semiconductors and metals increases with increase temperature
Correct Answer
Solution
The electrical resistance of metals depends upon temperature. Electrical resistance decreases with decrease in temperature and becomes zero near the absolute temperature. Material in this state is said to possess super conductivity.
