Question
Presence of defects such as vacancies in a crystal enhances its A. Stability B. Durability C. Elasticity D. Compatibility
Solution
The presence of defects such as vacancies in a crystal generally enhances its B. Durability.
Here's why:
-
Defects like vacancies are empty spaces in the crystal lattice where an atom or ion is missing.
-
These vacancies can move around within the crystal structure, allowing the material to deform under stress without breaking. This is a process known as plastic deformation.
-
Therefore, the presence of these defects can make the crystal more durable, as it can withstand more stress before breaking or failing.
-
However, it's important to note that too many defects can also weaken the material, so there's a balance to be struck.
So, the answer is B. Durability.
