The Solid State (part 1)

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.

Why do different solid have different properties? What is the role of intermolecular force? What is thermal energy? Explain few characteristic of solid state? Can solid be compressed if not why? Why do solid have more density then liquid and gases. Why do solid have low rate of diffusion?

We all are surrounded by large number of solids around us. The physical state of a substance depends upon the two opposite forces. Intermolecular force is forces of attraction which exist among the molecules. Thermal energy is the opposite force. It tends to keep the constituent particle apart. These two forces are just opposite. Solid are rigid in nature and have a definite volume. Solid are almost incompressible. Intermolecular distances in solid are short and intermolecular forces are strong.
