Glass is a

1. super-cooled liquid
2. gel
3. polymeric mixture
4. micro-crystalline solid

Correct answer: super-cooled liquid

Solution

Glass is often described as a super-cooled liquid because it has a disordered atomic structure similar to liquids, yet it behaves like a solid at room temperature, lacking a definite crystalline structure.
