Q. Which of the following defects decrease the density?
I. Interstitial defect $\quad\quad$II. Vacancy defect
III. Frenkel defect $\quad\quad$IV. Schottky defect

The Solid State

Solution:

In vacancy defect and Schottky defect, some lattice sites are vacant. Thus, mass decreases but volume remains the same. Hence, density decreases.
