The Solid State(part 2)

In this Unit, we shall discuss different possible arrangements of particles resulting in several types of structures. The correlation between the nature of interactions within the constituent particles and several properties of solids will also be explored. How these properties get modified due to the structural imperfections or by the presence of impurities in minute amounts would also be discussed.

The Solid State (part 2)

What is crystalline? What is amorphous solid? What is the difference between crystalline and amorphous solid? Which solid has well defined geometrical shapes? Which solid has long short order? Which solid has a sharp melting point? What does sharp melting point mean? Why crystalline solid do has high energy fusion? What does heat of fusion mean? What does isotropic nature mean?

The solid in which the constitute particle are systematically arranged through out are called crystalline solid. They have a well defined geometrical shape. In amorphous solid do not have regular or geometrical shape. The constitute particle have long range order however amorphous solid have short range order. The constitute solid have a sharp melting point. The melting point of amorphous solid is not sharp. The constitute solid have a high and fixed heat of fusion. However it’s not the same with amorphous solid.
