Q. The presence of point defects in a crystal:

क्रिस्टल में बिंदु दोष की उपस्थिति:

Increases density
घनत्व बढ़ाता है

Decreases density
घनत्व कम हो जाता है

Does not affect density
घनत्व को प्रभावित नहीं करता

Always creates color in the crystal
क्रिस्टल में सदैव रंग बनाता है

Point defects, like vacancies (missing atoms), reduce the number of atoms per unit volume, thus decreasing the overall density of the crystal.
