Which of the following defects decrease the density ?A. Interstitial d

1.	Which of the following defects decrease the density ?A. Interstitial defectB. Vacancy defectC. Frankel defectD. Schottky defect.
Answer» Correct Answer - B::D (b,d) Both these defects decrease the density of solids. In both the cases, some lattice sites remain vacant. As a result, the mass decreases but volume does not change. Therefore, density decreases in both the cases.
