Explain what curve 1 represents, and why it slopes backwards unlike the corresponding curve 1 in the last diagram. ~1000 C 3) What is the normal boiling point of this substance? Liquid water has the highest specific heat of all liquids except for NH3(True, False) True 2. For the following two questions consider the two lines on the phase diagram below: This is the phase diagram for carbon dioxide with some values marked on it: Solid carbon dioxide is commonly known as “dry ice”. _____ 9) What is the phase (s, l, … If you look at Figure \(\PageIndex{1}\), you will see that there are three lines, three areas marked "solid", "liquid" and "vapour", and two special points marked "C" and "T". On Crosbia, bolonium (Bg) and manasium (Ma) react together to form the compound tastegudum. 5. Directions: Refer to the phase diagram below when answering the following questions. Work in groups on these problems. If you think about the three lines which meet at that point, they represent the point that liquid, solid and gas coexist. For each of the questions on this worksheet, refer to the phase diagram for mysterious compound X. at which thermodynamically distinct phases occur and coexist at equilibrium (at topic later on in the course). Phase transitions occur along lines of equilibrium. Legal. _____ 9) What is the phase (s, l, g) of a substance at 0.75 atm and 100 °C? Explain why most solids have a very steep curve, sloping slightly forwards as pressure increases. A phase diagram(or equilibrium diagram) is a diagram with Tand composition as axes, showing the equilibrium constitution. 1. and . Describe what happens to the substance as you increase the temperature from point 6 to point 8. on the phase of a substance: The CURVES indicate the conditions of temperature and pressure under which “equilibrium” between different phases of a substance can exist. Watch the recordings here on Youtube! Worksheet – Phase Diagrams 1. What state(s) would the substance be in at each of points 2 to 5? Phase Diagram Worksheet Name: A phase diagram is a graphical way to depict the effects of pressure and temperature on the phase of a substance: The CURVES indicate the conditions of temperature and pressure under which "equilibrium" between different phases of a substance can exist. Mark on the diagram the areas corresponding to ice, liquid water, and water vapor. on the phase of a substance: The CURVES indicate the conditions of temperature and pressure under which “equilibrium” between different phases of a substance can exist. Have questions or comments? Part D – Phase Diagram for Tastegudum. 14. Material in this phase has _____ volume and _____ shape. Suppose at a much lower pressure, the substance was under the conditions at point 6. Name, and explain the significance of, the point C. Curve 1 can be thought of as showing the effect of pressure on melting point. Suppose the temperature was then increased on this substance at constant pressure. Point T on the diagram is called the triple point. Answer the questions below in relation to the following generic phase diagram. 2) What is the normal melting point of this substance? The molecular viscosity of water is less than most liquids at comparable temperatures (True, False) True 3. Phase Diagram Worksheet Name: A phase diagram is a graphical way to depict the effects of pressure and temperature on the phase of a substance: The CURVES indicate the conditions of temperature and pressure under which "equilibrium" between different phases of a substance can exist. temperature. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. is a graphical way to depict the effects of . 4. 15. c. Suppose the constant pressure was 1 atmosphere. At 1 atmosphere and room temperature (25 C), would you expect solid carbon dioxide to melt to the liquid phase, or sublime to the gas phase? Use this diagram … temperature. 2. at which thermodynamically distinct phases occur and coexist at equilibrium (at topic later on in the course). The temperature and pressure corresponding to this are known as the critical temperature and critical pressure. We'll discuss these when they become relevant. Some industrial process require carbon dioxide. A phase diagram is a type of chart used to show conditions (pressure, temperature, volume, etc.) Draw a small blue circle around the point that is the triple point for tastegudum. There are usually two major distortions. Use the diagram above to explain how that term arises. Part C – Phase Diagram for Carbon Dioxide. 0. Figure 1: A typical phase diagram. These diagrams (including this one) are nearly always drawn highly distorted in order to see what is going on more easily. and . Label the regions of the diagram that correspond to the solid, liquid, and vapor phases. (Write the names of these phases in the appropriate regions directly on the diagram.) Explain why boiling point increases with pressure (this is a little hard at this stage, but give it a try). The molecular viscosity of water is less than most liquids at comparable temperatures (True, False) True 3. phase diagram. PHASE DIAGRAM WORKSHEET . 1)What is the critical temperature of compound X? is a graphical way to depict the effects of . phase diagram. Phase Change Worksheet. Part A – Generic Phase Diagram. What useful information can you get from the diagram about the simple physical properties of the substance? Phase Diagram Worksheet Answers Refer to the phase diagram below when answering the questions on this worksheet: 1) Label the following on the phase diagram above: Solid phase, liquid phase, gas phase, triple point, critical point. Phase Diagram Worksheet. You should try to answer the questions without accessing the Internet. Water has the highest value of latent heat of evaporation of all substances (True, False) True 4. If the temperature was then increased at constant pressure, what state(s) would the substance be in at points 10, and 11? The phase diagram for bromine is shown below. Phase Diagram Worksheet Answers Refer to the phase diagram below when answering the questions on this worksheet: 1) Label the following on the phase diagram above: Solid phase, liquid phase, gas phase, triple point, critical point. 7) What are the values for temperature and pressure at STP? PHASE DIAGRAM WORKSHEET #2 Name_____ Period_____ Date_____ At standard temperature and pressure, bromine (Br 2) is a red liquid. The phase diagram for bromine is shown below. Directions: Refer to the phase diagram below when answering the following questions. Bromine sublimes when the temperature is –25 0C and the pressure is 101.3 kPa. At point A, the beginning of observations, the substance exists in a solid state. Give the state(s) at each of the points 4 to 8. What section represents the gas phase? The carbon dioxide … pressure. What letter represents the triple point? 2) What is the normal melting point of this substance?
