Understanding Interstitial Defects Hidden Spaces

The video tutorial explains that crystals are not perfect due to defects formed during crystallization. These defects arise from irregularities in the arrangement of particles and increase with temperature. Crystal defects are classified into point and line defects. Point defects include stoichiometric, impurity, and non-stoichiometric defects. Stoichiometric defects are further divided into vacancy and interstitial defects. Vacancy defects occur when lattice points are vacant, reducing crystal density, while interstitial defects occur when particles occupy interstitial sites, increasing density. The video highlights the impact of these defects on crystal properties.

Describe the relationship between temperature and the number of defects in crystals.
