FAQs on Fun Video: Amorphous & Crystalline Solids with Classifications Video Lecture - JEE

1. What are amorphous solids?
Ans. Amorphous solids are solids that lack a regular crystalline structure. They have an irregular arrangement of atoms or molecules and do not have a well-defined shape. Examples of amorphous solids include glass, rubber, and plastics.
2. How are crystalline solids different from amorphous solids?
Ans. Crystalline solids have a regular, repeating arrangement of atoms or molecules, while amorphous solids do not. Crystalline solids have a well-defined shape and sharp melting points, whereas amorphous solids do not have a clear melting point and tend to soften and flow gradually when heated.
3. What are the classifications of solids based on their atomic/molecular arrangement?
Ans. Solids can be classified into two categories, namely, crystalline and amorphous solids. Crystalline solids can be further classified into four types, namely, molecular solids, ionic solids, metallic solids, and covalent network solids.
4. What are the properties of crystalline solids?
Ans. Crystalline solids have a definite shape, a sharp melting point, and a regular, repeating arrangement of atoms or molecules. They are brittle and have a high melting point. They are also good conductors of heat and electricity, depending on their composition.
5. What are the properties of amorphous solids?
Ans. Amorphous solids do not have a well-defined shape or melting point. They have an irregular arrangement of atoms or molecules and tend to soften and flow gradually when heated. They are usually less brittle than crystalline solids and have lower melting points. They are also poor conductors of heat and electricity.
