Which solid structure has a definite and sharp melting point?

a) All types of solids

b) No type of solid

c) Amorphous solids

d) Crystalline solids

Solutions

Expert Solution

Answer : d) Crystalline solids

Explanation :

In the structure of crystalline solids the arrangement of unit cell is completely organized and the melts at a specified temperature.

While amorphous has irregular arrangements of unit cell which changes the specified melting temperature of amorphous solids.

Definite and sharp melting point of any solid it depends upon the the purity of solid. More pure solid melts a sharp melting point and vice versa.

d) Crystalline solids
