1.	Which of the folowings statements are not true ?A. Vacancy defect results in a decrease in the density of the substance.B. Intersitital defect results in an increase in the density of the substance .C. Impurity defect has no effect on the density of the substance.D. Frenkel defect results in an increase in the density of the substance.
Answer» Correct Answer - A::B::D © is not true because impurity defect changes the mass but not the volume. (d) is not true because Frenkel defect neither changes mass nor volume.
