Why is glass considered as a supercooled liquid?

Text Solution

Verified by Experts

Glass is amorphous and has a tendency to flow very slowly. This is supported by the fact that glass panes of windows of some old buildings are found to be slightly thicker at the bottom than at the top. So glass is considered as a supercooled liquid.
