solid states notes
FRIENDSWAY LEARNING CLASSES CHAPTER:- SOLID STATE SOLID- Solids are defined as substances that retain their shape, even when they are not confined. Substances usually assume the solid state of being at lower temperatures than they do when they are liquids, gases or plasmas. CLASSIFICATION ON THE BASIS OF ARRANGEMENT OF CONSTITUENT PARTICLES 1. Crystalline Solids:- A solid is said to be crystalline if its various constituent particles [ions, atoms, molecules] are arranges in a definite geometric pattern in the three dimensional space so that there is short as well as long range order of constituent particles.Example:- Sodium, Calcium, Stones, Gems, Wood etc. 2. Amorphous Solid:- If there is no regular arrangement of constituent particles or there is only the short range order of its constituent particles then the solid is called amorphous solid.Example:- Rubber, Glass, Pitch, Silica etc. 3. Isotropy:- In the amorphous solid...
