Study Cards on glass, liquid, crispiness

A glass and/or gel are still a liquid T/F
Describe a glass
Brittle and hard solid
What happens if the glass is porous?
Breaking will involve a complex series of small breakages; this is what we call crispiness
What is the difference on molecular scale between a glass and a liquid?
The molecules in a glass are (more or less) randomly oriented, but the difference is that they can hardly move.
Is a glass in thermodynamic equilibrium?
What does it mean that a glass in a vitrified liquid?
It means that it cannot respond anymore to the changes in its condition (e.g. Reduction in temperature), but would have a driving force to do so.
