Concept explainers
(a)
Interpretation:
To determine that how the given phase diagram should be modified so as to represent the melting of orthorhombic sulfur.
Concept introduction:
A phase transition refers to the transitions that occurs between
(b)
Interpretation:
To account for the given observation where rhombic sulfur is melted at 113oC and then it is heated such that the liquid sulfur gets freezed at 119oC upon cooling.
Concept introduction:
A phase transition refers to the transitions that occurs between solid, liquids and gas. There is a triple point that exists in a given phase diagram and at this point all the three states of matter are known to be coexist. The melting of a substance is said to occur when its state changes from solid to liquid. The reverse of melting is known as fusion or freezing where the state of the substance changes from liquid to solid.

- Phase diagrams for materials that have allotropes can be more complicated than those shown in the chapter. Use the phase diagram for carbon given here to answer the following questions. (a) How many triple points are present and what phases are in equilibrium for each? (b) Is there a single point where all four phases are in equilibrium? (c) Which is more stable at high pressures, diamond or graphite? (d) Which is the stable phase of carbon at room temperature and 1 atmosphere pressure?arrow_forwardThe 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_forwardFollow the step-wise process outlined in Problem 31 to calculate the amount of heat involved in condensing 100.00 g of benzene gas (C6H6) at 80.00C to liquid benzene at 25.00C. Use Tables 8.1 and 8.2 for the specific heat, boiling point, and heat of vaporization of benzene.arrow_forward
- The specific heat capacity of silver is 0.235 J/g K. Its melting point is 962 C, and its enthalpy of fusion is 11.3 kJ/mol. What quantity of energy, in joules, is required to change 5.00 g of silver from a solid at 25 C to a liquid at 962 C?arrow_forwardThe vapor pressure of ethanol, C2H5OH, at 50.0 C is 233 mmHg, and its normal boiling point at 1 atm is 78.3 C. Calculate the vapH of ethanol.arrow_forwardConsider the phase diagram and heating-curve graphs for Question 113. Draw corresponding heating curves for T1 to T2 at pressures P1 and P2. Label each phase and phase change on your heating curves.arrow_forward
