What other name is given to the amorphous solids ?

Options

A. Pseudo solids
B. True solids
C. Super cooled liquids
D. Super cooled solids

Answer

**Step-by-Step Solution:**

1. **Understanding Amorphous Solids**:
- Amorphous solids are materials whose particles are not arranged in a regular, repeating pattern. This lack of order distinguishes them from crystalline solids, which have a well-defined structure.

2. **Characteristics of Amorphous Solids**:
- The particles in amorphous solids exhibit irregular movement, leading to properties that differ from those of crystalline solids. Common examples include glass, rubber, and plastics.

3. **Identifying Alternate Names**:
- The question asks for another name given to amorphous solids. The options provided are:
- Pseudo-solids
- True-solids
- Super-cooled liquids
- Super-cooled solids

4. **Analyzing the Options**:
- **Pseudo-solids**: This term is often used to refer to amorphous solids due to their non-crystalline nature.
- **True-solids**: This term typically refers to crystalline solids, so it does not apply to amorphous solids.
- **Super-cooled liquids**: Glass, a common example of an amorphous solid, is sometimes referred to as a super-cooled liquid because it behaves like a liquid over long periods, despite being solid.
- **Super-cooled solids**: This term is not commonly used to describe amorphous solids.

5. **Conclusion**:
- Based on the analysis, the alternate names for amorphous solids include **pseudo-solids** and **super-cooled liquids**. Therefore, the correct answers are options 1 and 3.
