Exercise 2
Question 2
What makes a glass different from a solid such as quartz? Under what conditions could quartz be converted into glass?
The first difference between them is that quartz contains almost 99% silicon dioxide while glass contains only 80% silicon dioxide.
Secondly, glass has a irregular molecular structure while quartz has a symmetrical molecular structure.
Thirdly, quartz can withstand high temperature & pressure ,whereas glass is unstable at high temperature & pressure.
Fourthly, glass act as an insulator & do not conduct electricity,while quartz conducts electricity.
For the conversion of quartz into glass, the quartz has to be melted & cooled rapidly.
