Answer:
(1) Crystalline solid is a homogeneous solid and it has long range order of regular pattern of arrangement which repeats periodically over entire crystal.
(2) The interatomic or intermolecular forces are identical, hence the thermal energy required to break the regular structure by overcoming the intermolecular forces is uniform throughout.
(3) Hence the heat and temperature needed to melt the solid are same, and therefore solids have sharp melung points.
