Which one of the following property is attributed to amorphous solid ?

Options

A. Isotropy
B. Anisotropy
C. Sharp melting point
D. Long range order

Answer

To determine which property is attributed to amorphous solids, let's analyze the given options step by step.

### Step 1: Understand the properties of amorphous solids
Amorphous solids are characterized by a lack of long-range order in their structure. Unlike crystalline solids, they do not have a well-defined geometric shape or a repeating pattern throughout the material.

### Step 2: Analyze the options
1. **Isotropy**: This refers to materials that have the same physical properties in all directions. Amorphous solids are isotropic because their disordered structure does not favor any particular direction.

2. **Anisotropy**: This is the opposite of isotropy, where materials exhibit different properties in different directions. This property is typically associated with crystalline solids.

3. **Sharp melting point**: Crystalline solids have a sharp melting point due to their ordered structure. Amorphous solids, on the other hand, do not have a sharp melting point; they soften over a range of temperatures.

4. **Long-range pattern**: Amorphous solids do not have a long-range order in their atomic arrangement, which is a characteristic of crystalline solids.

### Step 3: Conclusion
From the analysis, the only property that is attributed to amorphous solids is **isotropy**. Therefore, the correct answer is:

**Option 1: Isotropy**
