Question:
Which of the following is an amorphous material?
Which of the following is an amorphous material?
Show Hint
Amorphous means "without shape" or "disordered"—think of glass as a supercooled liquid.
Updated On: Jul 4, 2026
- Brass
- Glass
- Aluminium
- Gold
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Amorphous materials lack the long-range periodic order of atoms that characterizes crystalline solids.
Step 2: Meaning
Metals and alloys typically solidify into organized lattice structures (FCC, BCC, etc.).
Step 3: Analysis
Gold, Aluminium, and Brass (a Copper-Zinc alloy) are crystalline. Glass is a non-crystalline solid where the atomic structure is disordered, similar to a liquid but rigid.
Step 4: Conclusion
Glass is the standard example of an amorphous material among the provided options. Final Answer: (B)
