Amorphous solids can also be callled ………….. .

Options

A. pseudo solids
B. true solids
C. super cooled liquids
D. super cooled solids.

Answer

To answer the question "Amorphous solids can also be called …………..", we will analyze the properties of amorphous solids and identify the correct terminology associated with them.

### Step-by-Step Solution:

1. **Understanding Amorphous Solids**:
- Amorphous solids are materials that do not have a long-range order or a regular arrangement of particles. Unlike crystalline solids, which have a well-defined geometric structure, amorphous solids exhibit a disordered arrangement.

2. **Examples of Amorphous Solids**:
- Common examples include glass, rubber, and certain plastics. These materials may appear solid but lack the crystalline structure.

3. **Properties of Amorphous Solids**:
- Amorphous solids can flow over long periods, albeit very slowly. For instance, glass can deform under its own weight over many years, which is often cited as evidence of its amorphous nature.

4. **Terminology**:
- Amorphous solids are often referred to as "pseudo solids" because they exhibit solid-like physical appearance but do not possess the definitive solid properties.
- They can also be called "supercooled liquids" because they have the ability to flow like liquids, but they are in a solid state at room temperature.

5. **Conclusion**:
- Based on the definitions and properties discussed, amorphous solids can be referred to as "pseudo solids" and "supercooled liquids".

### Final Answer:
Amorphous solids can also be called **pseudo solids** and **supercooled liquids**.
