140 C. Temperature ( o C) 120 D. 80. The formula becomes: Example Question #4: Energy Of Phase Changes. All Rights Reserved. How much heat must be added to raise a sample of 100g of water at 270K to 280K? The diagram below shows the cooling of a substance starting with the substance at a temperature above it. Describe the change in kinetic energy of the substance during segments A and segment B?
Boiling is a phase change from liquids to gas. Using the heating curve, determine which segment(s) relate to an increase in potential energy. Copyright©2010 E3 Scholastic Publishing. There is a lower heat of fusion at higher elevation. What is the melting point of the substance? Phase change diagram answer key of life. What is the phase or phases of the substance during segment C? Therefore the potential energy is increasing during segments 2 and 4. In the given heating curve, which segment(s) correlate to a mixture of phases? Therefore there is a mix of molecules during segments 2 and 4. When kinetic energy is increasing molecules are simply moving faster. The beginning of segment 5.
Therefore the substance is boiling during segment 4. Hydrogen bonds are easier to disrupt at high elevation. The atmospheric pressure is lower at high elevations. The substance is losing heat at a rate of 155 Joules per minute. 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. Phase change diagram answer key.com. What is the total length of time that the substance undergoes fusion? At which segment or segments is the substance average kinetic energy increasing?
Page 19 - Surviving Chemistry Workbook Preview. Water has a higher vapor pressure at high elevation. How much heat did the substance lose to completely change from liquid to solid?
In this case, gas phase is the highest energy phase, and liquids is the next highest. So, the potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing. Which segment represents only the liquid phase? Therefore we are looking for a segment that is flat (because the potential energy is increasing) and that is between the liquid and gas phases. All AP Chemistry Resources. As condensation forms on a glass of ice water, the temperature of the air surrounding the glass __________. When vapor pressure is equal to the atmospheric pressure, water boils. 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. As a substance condenses from the gas phase to the liquid phase, it loses energy in the form of heat loss.
B C. Temperature ( o C) 50. At which segment or segments is the substance exists in two phases? Therefore only the segments that are at an incline will have the substance in just one phase. 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44. Therefore the kinetic energy increases whenever the temperature is increasing.
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. Which segment represents the substance as it is boiling? Explain your answer.
