Question

Q.11- why are amorphous solids considered as supercooled liquid?
n 12 how many octahedral voids are there in in 1 mole of a compound having cubic closed packed structur​

Answer 1

Answer:

Glass is basically an amorphous solid. It does not form a crystalline structure. So, the constituent particles of the glass can move. In regular solids, there is no movement of constituent particles under normal conditions.Due to this fluidity property, glass is called as supercooled liquid. Glass can be considered as a liquid of extremely high viscosity.The evidence of the fact can be seen in the windows getting thicker at bottom over a period of time.
