Two dimensional structure of (a) quartz and (b) quartz glass , Distinction between Crystalline and Amorphous Solids
Refractive index of a solid is observed to have the same value along all directions. Comment on the nature of this solid. Would it show cleavage property?
'Stability of a crystal is reflected in the magnitude of its melting point'. Comment. Collect melting points of solid water, ethyl alcohol, diethyl ether and methane from a data book. What can you say about the intermolecular forces between these molecules?
The relation a ≠ b ≠ c and α ≠ β ≠ γ represents which crystal system?
What makes a glass different from a solid such as quartz? Under what conditions could quartz be converted into glass?
