Which of the following statements about amorphous solid is incorrect ?

Options

A. They melt over a range of temperature
B. They are anisotropic
C. There is no orderly arrangement of particles
D. They are rigid and incompressible

Explanation

To determine which statement about amorphous solids is incorrect, let's analyze each statement step by step.

### Step 1: Understand Amorphous Solids
Amorphous solids are materials in which the particles are not arranged in a regular pattern. This irregular arrangement leads to different properties compared to crystalline solids, which have a well-defined structure.

### Step 2: Analyze Each Statement
1. **Statement 1: Amorphous solids melt over a range of temperatures.**
- **Analysis:** This statement is correct. Amorphous solids do not have a sharp melting point; instead, they soften and melt over a range of temperatures due to their irregular structure.
