प्रश्न
The sharp melting point of crystalline solids is due to ______.
पर्याय
a regular arrangement of constituent particles observed over a short distance in the crystal lattice
a regular arrangement of constituent particles observed over a long distance in the crystal lattice
same arrangement of constituent particles in different directions
different arrangement of constituent particles in different directions
उत्तर
The sharp melting point of crystalline solids is due to a regular arrangement of constituent particles observed over a long distance in the crystal lattice.
Explanation:
A solid is said to be crystalline if the various constituent structural units (atoms, ions or molecules) of which the solid is made, are arranged in a definite geometrical pattern within the solid.
The type of forces in crystalline solids are of long range order due to which they have sharp melting point.
