what is frenkal defect and what is its effect on density of a soild
Answers
Answer:
In this defect, an ion is displaced from its lattice place to an interstitial place. So there is no loss or gain of ions in its lattice structure. We all know that density is nothing but mass per volume. As there is no change in their mass and volume so there is no effect in the density of the solid due to this defect.
Answer:
A Frenkel defect is a type of point defect in crystalline solids named after its discoverer Yakov Frenkel. The defect forms when an atom or smaller ion leaves its place in the lattice, creating a vacancy, and becomes an interstitial by lodging in a nearby location.When a substance is heated its volume increases and so the density decreases. In solids, increase in volume is negligible and hence decrease in density too. In liquids and gases, as the temperature increases, volume increases and therefore density decreases considerably.
