Boiling is a phase change from liquids to gas. The beginning of segment 5. Therefore there is a mix of molecules during segments 2 and 4. What is the phase or phases of the substance during segment C?
Which segment or segments represents a time when the substance is in one phase? Using the heating curve, determine which segment(s) relate to an increase in potential energy. Example Question #10: Energy Of Phase Changes. Topics for each state include: pressure conversions, relationship between Kelvin and kinetic energy, phase changes, intermolecular forces, types of solids, phase diagrams and much more! Phase change diagram answer key lime. The atmospheric pressure is lower at high elevations. B C. Temperature ( o C) 50. Copyright©2010 E3 Scholastic Publishing. 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.
The diagram below shows the cooling of a substance starting with the substance at a temperature above it. So, the potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing. When kinetic energy is increasing molecules are simply moving faster. Which segment represents the substance as it is boiling? Phase change diagram worksheet answer key. The flat areas of the graph represent areas in which heat is being added, but there is no corresponding increase in temperature. What is the total length of time that the substance undergoes fusion? The formula becomes: Example Question #4: Energy Of Phase Changes.
The higher the elevation, the denser water is. Phase change diagram explained. At which segment or segments is the substance average kinetic energy increasing? The following fomula gives the heat needed to generate a given temperature change for a substance of known specific heat capacity: where is the heat input in Joules, is the mass of the sample in grams, and is the specific heat capacity in. The enthalpy of vaporization gives the amount of energy required to evaporate a liquid at its boiling point, in units of energy per mole. The atmospheric pressure is lower at high elevation, so water boils at a lower temperature.
Increasing temperature means that vapor pressure increases as well. Using the heat curve, define the segment time(s) that the kinetic energy of the substance is increasing. How much heat did the substance lose to completely change from liquid to solid? Therefore only the segments that are at an incline will have the substance in just one phase. The given heating curve represents a substance in phases solid, liquid, and gas. As a substance condenses from the gas phase to the liquid phase, it loses energy in the form of heat loss. Hydrogen bonds are easier to disrupt at high elevation. Remember, temperature is a measure of the average kinetic energy. Therefore, when the potential energy is increasing is when the molecule is changing phases. Therefore the kinetic energy increases whenever the temperature is increasing. Explain your answer. So, the kinetic energy is increasing during segments 1, 3, and 5. States of Matter - Intermolecular Forces, Kinetic Molecular Theory, Temperature, Pressure, Solids, Liquids, Gases, Distance learning, Remote learningThis bundle of lesson plans will teach your students about Kinetic Molecular Theory for solids, liquids, and gases.
Potential energy of the substance remains constant during which segment or segments? Therefore the substance is boiling during segment 4. Describe the change in kinetic energy of the substance during segments A and segment B? In this case, gas phase is the highest energy phase, and liquids is the next highest. What is the total length of the time that the substance exists only as a liquid? Page 19 - Surviving Chemistry Workbook Preview. Therefore the kinetic energy will be the highest when the temperature is the highest. 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? 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.
