Set E: Phase change diagram Objective: To test your ability to interpreted phase change diagrams. B C. Temperature ( o C) 50. Therefore, when the potential energy is increasing is when the molecule is changing phases. What is the total length of the time that the substance exists only as a liquid? Remember, temperature is a measure of the average kinetic energy. There is a lower heat of fusion at higher elevation. Therefore there is a mix of molecules during segments 2 and 4. The atmospheric pressure is lower at high elevation, so water boils at a lower temperature. 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. The temperature remains constant throughout a phase change, thus the final temperature would still be 100°C. Phase change diagram answer key figures. Therefore only the segments that are at an incline will have the substance in just one phase. Finally, because liquids are higher in energy than solids, and lower in energy than gasses the middle slanted line must be the liquid phase.

Phase Change Diagram Explained

The beginning of segment 5. Therefore the kinetic energy increases whenever the temperature is increasing. Copyright©2010 E3 Scholastic Publishing. Describe the change in kinetic energy of the substance during segments A and segment B? All Rights Reserved. Step-by-step PowerPoint notes will guide your stu. Rather, this added heat energy is used to break the intermolecular forces between molecules/atoms and drive phase changes. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21. Phase change diagram answer key lime. 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. Why does water boil at a lower temperature at high elevation?

Phase Change Diagram Answer Key Figures

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. Therefore the substance is boiling during segment 4. Boiling is a phase change from liquids to gas. Phase change diagram answer key.com. 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. In the given heating curve, which segment(s) correlate to a mixture of phases? Hydrogen bonds are easier to disrupt at high elevation.

Phase Diagram Worksheet Answer Key

Using the heat curve, define the segment time(s) that the kinetic energy of the substance is increasing. 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. Which segment represents the substance as it is boiling?

What is the melting point of the substance? So, the potential energy of the molecules will increase anytime energy is being supplied to the system but the temperature is not increasing. 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44. When kinetic energy is increasing molecules are simply moving faster.

Is the total length of time it took for the substance to change from liquid to solid? The enthalpy of vaporization gives the amount of energy required to evaporate a liquid at its boiling point, in units of energy per mole. At which segment or segments is the substance exists in two phases? Therefore the kinetic energy will be the highest when the temperature is the highest. The substance is losing heat at a rate of 155 Joules per minute. So, the kinetic energy is increasing during segments 1, 3, and 5. 140 C. Temperature ( o C) 120 D. 80.

Explain your answer. Which segment represents only the liquid phase? 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 __________.

The higher the elevation, the denser water is. How much heat must be added to raise a sample of 100g of water at 270K to 280K? Which segment or segments represents a time when the substance is in one phase? 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. Heat is transferred from the water to the air, resulting in an increase in the temperature of the air. The specific heat capacity of water is, and water's heat of fusion is.

What is the phase or phases of the substance during segment C? The given heating curve represents a substance in phases solid, liquid, and gas. At what temperature are the solid and liquid phases exist at equilibrium? Water has a higher vapor pressure at high elevation. Potential energy of the substance remains constant during which segment or segments?

Margaret Bodde, a film producer and executive director of the Film Foundation, says "With Marty, what is so remarkable is his dedication to preservation and film as culture and an art form. From the context of the first paragraph what characteristic does the author attribute to the tastes of the majority? Check whose tone or attitude you're focused on.
