FAQs on One Shot: Properties of Solid State Video Lecture - Chemistry Class 12 - NEET

1. What are the properties of solid state?
Ans. Solid state refers to the state of matter in which particles are closely packed together and have a fixed shape and volume. Some properties of solid state include: - Definite shape and volume: Solids have a fixed shape and volume due to the close arrangement of particles. - High density: The particles in solids are tightly packed, leading to high density compared to liquids and gases. - Strong intermolecular forces: The particles in solids are held together by strong intermolecular forces, resulting in a stable structure. - Low compressibility: Solids are difficult to compress due to the close arrangement of particles. - High melting and boiling points: Solids generally have high melting and boiling points due to the strong forces between particles.
2. How is the shape of solids maintained?
Ans. The shape of solids is maintained due to the strong intermolecular forces between particles. These forces, such as ionic, covalent, or metallic bonds, hold the particles in a fixed position. As a result, solids have a definite shape and do not easily change their form under normal conditions. The arrangement and organization of particles in solids contribute to their specific shape.
3. Why do solids have high density compared to liquids and gases?
Ans. Solids have high density compared to liquids and gases because the particles in solids are tightly packed together. The intermolecular forces between particles in solids are strong, causing them to be closely spaced. This close arrangement of particles results in a higher mass per unit volume, leading to a higher density. In contrast, liquids and gases have particles that are more spread out, resulting in lower densities.
4. What is the significance of strong intermolecular forces in solids?
Ans. Strong intermolecular forces in solids are significant as they contribute to the stability and properties of solids. These forces, such as ionic, covalent, or metallic bonds, hold the particles together in a solid state. The presence of strong intermolecular forces gives solids their high melting and boiling points, as well as their rigidity and resistance to deformation. Additionally, these forces determine other properties of solids, such as electrical conductivity and thermal conductivity.
5. Why are solids difficult to compress?
Ans. Solids are difficult to compress due to the close arrangement of particles and the strong intermolecular forces between them. The particles in solids are already tightly packed, leaving little space for compression. When an external force is applied to a solid, the particles can only move slightly, resulting in a minimal change in volume. The strong intermolecular forces further resist any attempt to compress the solid, making it challenging to compress solids compared to liquids and gases.
