Interpretation:
Solid: Solid is a sample of matter that retains its shape and density when not confined. Stronger force of attraction exists between atom/ions/ molecules.
Liquid: A liquid is a sample of matter that conforms to shape of container in which aquires a defined surface in the presence of gravity. In this state weaker force exist between atoms/ ions/ molecules.
Gas: A gas is a sample of matter that conforms to the shape of container in which it is placed and acquires whole volume of container.
Negligible force of attraction exists between atoms/ions/molecules.
Supercritical fluid: Fluid over its critical temperature and pressure exhibiting good solvent power.
Concept used introduction:
A generic diagram which shows that state of general matter with change in pressure or temperature or both. At a particular temperature or pressure you can find out the state of matter with the help of phase diagram.
To determine:
Identify the states present at points through a to g in the phase diagram show here.

- The phase diagram for water over a relative narrow pressure and temperature range is given in Figure 9.19. A phase diagram over a considerably wider range of temperature and pressure (kbar) is given nearby. This phase diagram illustrates the polymorphism of ice, the existence of a solid in more than one form. In this case, Roman numerals are used to designate each polymorphic form. For example, Ice I, ordinary ice, is the form that exists under ordinary pressures. The other forms exist only at higher pressures, in some cases extremely high pressure such as Ice VII and Ice VIII. Using the phase diagram, give the approximate P and T conditions at the triple point for Ice III, Ice V, and liquid water. Determine the approximate temperature and pressure for the triple point for Ices VI, VII, and VIII. What is anomalously different about the fusion curves for Ice VI and Ice VII compared to that of Ice I? What phases exist at 8 kbar and 20 °C? At a constant temperature of −10 °C, start at 3 kbar and increase the pressure to 7 kbar. Identify all the phase changes that occur sequentially as these conditions change. Explain why there is no triple point for the combination of Ice VII, Ice VIII, and liquid water.arrow_forwardExplain why liquids assume the shape of any container into which they are poured, whereas solids are rigid and retain their shape.arrow_forwardWhat phase changes will take place when water is subjected to varying pressure at a constant temperature of 0.005 C?
