Concept explainers
(a)
Interpretation:
Whether the three phases of water would attain equilibrium at some temperature or not is to be determined.
Concept introduction:
The phase diagram is a combination of
(b)
Interpretation:
Whether the temperature would be higher, lower or the same as the triple point for pure water is to be determined.
Concept introduction:
The phase diagram is a combination of liquid-gas, solid-liquid, and solid-gas curves and determines the effect of temperature and pressure on the phase of a substance. It is a graphical representation of the physical states of the substances under different conditions of temperature and pressure. The regions around the different lines show the phase of the substance and the lines indicate that the different phases are in equilibrium. The triple point is the temperature at which three phases of the substance coexist in the equilibrium.
(c)
Interpretation:
Whether ice would sublime at few degrees below the freezing point or not is to be determined.
Concept introduction:
The freezing point is the temperature at which both the solid and liquid phases coexist in equilibrium. It is the temperature at which the vapor pressure of the substance in the liquid state becomes equal to the vapor pressure in a solid state.
(d)
Interpretation:
Whether the liquid will have the same vapor pressure than that in figure 12.7 or ot is to be determined.
Concept introduction:
Vapor pressure is the pressure exerted by the vapors when the liquid and vapor phase are in the equilibrium with each other. Vapor pressure depends upon the temperature and remains after the gas is compressed.
