Concept explainers
a)
Interpretation:
Whether ability to cleave along plane differ in glassy and crystalline phases of substance has to be determined.
Concept Introduction:
Glass term in ceramic technology contrasts with crystalline solid. Glass is also known as amorphous material. It gets rubbery as temperature increases. Amorphous solid do not have well-defined faces unless they get cut or get molded.
b)
Interpretation:
Whether rigidity differs in glassy and crystalline phases of substance or not has to be determined.
Concept Introduction:
Refer to part (a).
c)
Interpretation:
Whether melting point differs in glassy and crystalline phases of substance or not has to be determined.
Concept Introduction:
Refer to part (a).
d)
Interpretation:
Whether transparency differs in glassy and crystalline phases of substance or not has to be determined.
Concept Introduction:
Refer to part (a).
