You are given the melting point and boiling point of an unknown substance. You are to create a heating curve from the data provided below. You may describe how to graph it if you can't graph it.
Here is the data for you to use to create your heating curve:
Melting point = 45°C
Boiling point = 85°C
Minimum temperature = 0°C
Maximum temperature = 110°C
Energy is absorbed but there is no numeric data to add, just include the unit for energy in your axis label
Using your heating curve, place the following labels directly on the curve - you will use the same curve you created yesterday, just add these labels as embellishments to your existing heating curve: if you cant make a graph, explain where everything will go
mark the minimum temperature on the curve with the letter A (1pt)
mark the maximum temperature on the curve with the letter F (1pt)
mark the beginning of the phase change from solid to liquid with the letter B (1pt)
mark the ending of the phase change from solid to liquid with the letter C (1pt)
mark the beginning of the phase change from liquid to gas with the letter D (1pt)
mark the ending of the phase change from liquid to gas with the letter E (1pt)
mark where the substance is in the solid phase with the letter X (1pt)
mark where the substance is in the liquid phase with the letter Y (1pt)
mark where the substance is in the gas phase with the letter Z (1pt)
mark any place on the curve where the kinetic energy is increasing with the letters and arrow pointing up: KE↑ (6pts)
mark any place on the curve where the potential energy is increasing with the letters and arrow pointing up: PE↑ (4pts)
To create the heating curve based on the given data:
1. Start the graph with temperature on the y-axis (from 0°C to 110°C) and energy (in units) on the x-axis.
2. Draw a horizontal line at 45°C to mark the melting point (label as A).
3. Draw a horizontal line at 85°C to mark the boiling point (label as F).
4. Draw a diagonal line from 0°C to 45°C to represent the substance going from solid to liquid (label as B to C).
5. Draw a diagonal line from 45°C to 85°C to represent the substance going from liquid to gas (label as D to E).
6. Mark the phase change from solid to liquid with letter B and from liquid to gas with letter D.
7. Mark the end of the phase change from solid to liquid with letter C and from liquid to gas with letter E.
8. Label areas of solid phase with letter X, liquid phase with letter Y, and gas phase with letter Z.
9. Use arrows with KE↑ to show where kinetic energy is increasing and with PE↑ to show where potential energy is increasing.
where would the KE↑ and PE↑ go?
The KE↑ and PE↑ labels would go at points on the heating curve where either kinetic energy or potential energy is increasing.
1. Look for the points on the curve where the temperature is increasing (indicating an increase in kinetic energy) without a change in phase.
2. Label those points with KE↑ to show that kinetic energy is increasing.
3. Look for the points on the curve where the substance is undergoing a phase change (solid to liquid or liquid to gas).
4. Label those points with PE↑ to show that potential energy is increasing during the phase change.
Use the heating curve to answer these questions
as temperature blank 1 kinetic energy blank 2. This demonstrates blank 3.
blank 1: A. Decreases B. Increases C. Remains the same
blank 2: A. Decreases B. Increases C. Remains the same
blank 3: A. An inverse relationship B. No identifiable relationship C. A direct relationship
as temperature increases blank 1 kinetic energy blank 2. This demonstrates blank 3.
blank 1: B. Increases
blank 2: B. Increases
blank 3: C. A direct relationship
While holding kinetic energy constant, as thermal energy blank 1, potential energy blank 2. This demonstrates blank 3.
blank 1: A. Decreases B. Increases C. Remains the same
blank 2: A. Decreases B. Increases C. Remains the same
blank 3: A. An inverse relationship B. No identifiable relationship C. A direct relationship
While holding kinetic energy constant, as thermal energy increases, potential energy remains the same. This demonstrates blank 3.
blank 1: B. Increases
blank 2: C. Remains the same
blank 3: B. No identifiable relationship
Looking at the temperature interval from 0°C to 44°C, the kinetic energy blank 1, the potential energy blank 2, the thermal energy blank 3, the particle movement blank 4, and the phase of matter
options: changes, decreases, does not change, increases.
Looking at the temperature interval from 0°C to 44°C, the kinetic energy increases, the potential energy does not change, the thermal energy increases, particle movement increases, and the phase of matter changes from solid to liquid.
Looking at the temperature of 45°C, the kinetic energy Response area, the potential energy Response area, the thermal energy Response area, and the phase of matter
options: changes, decreases, does not change, increases.
