How can glass be liquid if it is so hard |
|
Answer» tion:Glass is not a liquid in the strictest sense of the word. But it is also not a standard solid. The CHEMISTRY of glass is complex and research is ongoing, but the current consensus is that glass is a PHASE of matter all its own, known as an "AMORPHOUS solid". Scientists refer to any amorphous solid as a "glass". Glass transitions are highly complex and cannot be treated in the same way as traditional phase transitions, according to the TEXTBOOK "Glasses and the Glass Transition" by Ivan S. Gutzow. |
