Amorphous solids do not have sharp melting points. Explain.

Explanation

(1) Amorphous solids do not have perfectly ordered crystalline structure.
(2) They have short range order of regular pattern hence periodically repeating regular pattern is over a short distance.
(3) Hence the temperature needed to melt the solid is not same, therefore amorphous solids do not have sharp melting points but melt over a range of temperature.
