In this case it is labeled as segment 3. Using the heat curve, define the segment time(s) that the kinetic energy of the substance is increasing. Explain your answer. Therefore the kinetic energy will be the highest when the temperature is the highest. When kinetic energy is increasing molecules are simply moving faster. Phase change diagram answer key strokes. The beginning of segment 5. When the kinetic energy is increasing (the temperature is also increasing) the substance is not going through a phase change. The enthalpy of vaporization gives the amount of energy required to evaporate a liquid at its boiling point, in units of energy per mole. Is the diagram a heating curve of water or of a different substance? Example Question #10: Energy Of Phase Changes.
What is the melting point of the substance? However, in the event of a phase change (water melts at 273K), the heat of fusion or vaporization must be added to the total energy cost. When vapor pressure is equal to the atmospheric pressure, water boils. Why does water boil at a lower temperature at high elevation? How much heat must be added to raise a sample of 100g of water at 270K to 280K? Therefore, when the potential energy is increasing is when the molecule is changing phases. Phase change diagram answer key figures. In this case, gas phase is the highest energy phase, and liquids is the next highest. At which segment or segments is the substance average kinetic energy increasing?
0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21. Boiling is a phase change from liquids to gas. The total energy requirement to heat a given amount of steam is found by mulitplying the the number of moles to be vaporized by the energy of vaporization per mole. Water has a higher vapor pressure at high elevation. Hydrogen bonds are easier to disrupt at high elevation.
How much heat did the substance lose to completely change from liquid to solid? What is the total length of time that the substance undergoes fusion? The higher the elevation, the denser water is.
The atmospheric pressure is lower at high elevations. At which segment or segments is the substance exists in two phases? Is the total length of time it took for the substance to change from liquid to solid? B C. Temperature ( o C) 50. Heat is transferred from the water to the air, resulting in an increase in the temperature of the air. Is impossible to determine. Therefore the kinetic energy increases whenever the temperature is increasing. Phase diagram worksheet answer key. All AP Chemistry Resources. As a substance condenses from the gas phase to the liquid phase, it loses energy in the form of heat loss.
Step-by-step PowerPoint notes will guide your stu. Potential energy of the substance remains constant during which segment or segments? The diagram below shows the cooling of a substance starting with the substance at a temperature above it. How much energy is required to boil 9 moles of liquid water at its boiling point, and what is the temperature of the water vapor product? As condensation forms on a glass of ice water, the temperature of the air surrounding the glass __________. What is the phase or phases of the substance during segment C? The atmospheric pressure is lower at high elevation, so water boils at a lower temperature. Copyright©2010 E3 Scholastic Publishing. So, the potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing. In the heating curve shown above, at what point do the molecules have the highest kinetic energy? Increasing temperature means that vapor pressure increases as well.
