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

Options

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

Explanation

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

### Step-by-Step Solution:

1. **Understanding Amorphous Solids**:
- Amorphous solids are materials that lack a long-range order in their atomic arrangement. Unlike crystalline solids, they do not have a definite geometric shape or a well-defined melting point.

2. **Identifying Alternative Names**:
- Amorphous solids are often referred to as "pseudo solids". This term indicates that while they exhibit some properties of solids, they do not possess the true characteristics of crystalline solids.

3. **Exploring Other Terms**:
- Another term associated with amorphous solids is "supercooled liquids". This term is used because, under certain conditions, amorphous solids can flow over time, similar to liquids. For example, glass, which is an amorphous solid, can flow very slowly, leading to thicker bases in old window panes.

4. **Conclusion**:
- Based on the characteristics and behavior of amorphous solids, they can be correctly referred to as "pseudo solids" and "supercooled liquids". Thus, the correct answers to the question are:
- Pseudo solids
- Supercooled liquids

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