Define the term "amorphous". Give a few example of amorphous solids.

Explanation

### Step-by-Step Solution:

1. **Definition of Amorphous:**
- The term "amorphous" is derived from the Greek word "amorphos," which means "without form." In the context of solids, it refers to materials that lack a well-defined crystalline structure.

2. **Characteristics of Amorphous Solids:**
- Amorphous solids are characterized by the absence of a long-range order in the arrangement of their particles. While the particles are closely packed, they do not exhibit a regular, repeating pattern like that found in crystalline solids. This irregular arrangement leads to unique physical properties.
