Which of the following defects decrease ...

Which of the following defects decrease the density ?

A

Interstitial defect

B

Vacancy defect

C

Frankel defect

D

Schottky defect.

Text Solution

Verified by Experts

The correct Answer is:
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.
