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).

Chemical Principles: The Quest for Insight
- What is the composition, in atom percent, of an alloy that contains 44.5 lbm of silver, 83.7 lbm of gold, and 5.3 lbm of Cu?arrow_forwardDraw and explain pressure-density phase diagram for CO2.arrow_forward>Explain why the viscosity of liquid sulfur increases with increasing temperature initially, but then decreases upon further increases in temperature.arrow_forward
- Write the difference between ferromagnetism and anti-ferromagnetism.arrow_forwardSteam distillation was performed to obtain geraniol (MM = 154.25 g/mol) from dried rose petals. At 99.25℃, the vapor pressure of water is 714 mmHg while that of geraniol was determined to be 46 mmHg. Determine the theoretical mass of geraniol that will distill per 100 g of water. If 150 g of dried rose petals were used, calculate the percent yield of the distillation.arrow_forwardThe later halogens form pentafluorides: ClF5, BrF5, andIF5. At 0°C, one of these is a solid, one a liquid, and one agas. Specify which is which, and explain your reasoning.arrow_forward
