- Explain why 15 g of steam at 100C melts more ice than 15 g of liquid water at 100C.arrow_forwardWhite phosphorus, P4, is normally a white, waxy solid melting at 44C to a colorless liquid. The liquid has a vapor pressure of 400.0 mmHg at 251.0C and 760.0 mmHg at 280.0C. What is the heat of vaporization of this substance?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_forward
- Sketch a phase diagram for O2 from the following information: normal boiling point, 90.18 K; normal melting point, 54.8 K; and triple point, 54.34 K at a pressure of 2 mm Hg. Very roughly estimate the vapor pressure of liquid O2 at 196 C, the lowest temperature easily reached in the laboratory. Is the density of liquid O2 greater or less than that of solid O2?arrow_forwardArrange the following substances in order of increasing strength of crystal forces: CO2, KCl, H2O, N2, CaO.arrow_forwardSilicon carbide, SiC, is a very hard, high-melting solid. What kind of crystal forces account for these properties?arrow_forward
- An amorphous solid can sometimes be converted to a crystalline solid by a process called annealing. Annealing consists of heating the substance to a temperature just below the melting point of the crystalline form and then cooling it slowly. Explain why this process helps produce a crystalline solid.arrow_forwardAnswer the following questions using Figure 11.12: (a) What is the approximate equilibrium vapor pressure of water at 60 C? Compare your answer with the data in Appendix G. (b) At what temperature does water have an equilibrium vapor pressure of 600 mm Hg? (c) Compare the equilibrium vapor pressures of water and ethanol at 70 C. Which is higher? Figure 11.12 Vapor pressure curves for diethyl ether [(C2H3)2O], ethanol (C2H5OH), and water. Each curve represents conditions of T and P of which the two phases, liquid and vapor, are in equilibrium. These compounds exist as liquids for temperatures and pressures to the left of the curve and as gases under conditions to the right of the curve. (See Appendix G for vapor pressures for water of various temperatures.)arrow_forwardPhase 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_forward
