Study Notes
Physical States of Matter
- Matter can exist in three physical states: solid, liquid, and gas.
Characteristics of Solids
- Solids have definite volume and definite shape.
- Atoms, molecules, or ions in solids are tightly held in an ordered arrangement.
Types of Solids
- Examples of solids include diamond, metals, and plastics.
- Most substances used in daily life are in the solid state.
Importance of Understanding Solid Structure
- Understanding the relation between the structure of solids and their properties is useful in synthesizing new solid materials with different properties.
Classification of Solids
- Solids can be classified into two major types based on the arrangement of their constituents.
- The two types of solids are:
Crystalline Solids
- The term "crystal" comes from the Greek word "krystallos", meaning clear ice.
- Crystalline solids are bounded by many flat, symmetrically arranged faces.
Amorphous Solids
- No specific arrangement of their constituents.
