Energy Forms and Changes

For this assignment, you will participate in an online simulation and complete a worksheet based on your activity in the simulation by answering questions and including screenshots of your work. You must be logged into Blackboard to access the simulation.

Open the Energy Forms and Changes Interactive Simulation found in the Syllabus and Study Guide under the
Unit IV Lab Assignment.
Start this exercise by clicking on “Intro.” (We will not be exploring the “Systems” part of this simulation.)
Click the “Energy Symbols” box in the upper right hand corner. (Clicking the “link heaters” is optional.)
Play with the simulator. Get comfortable with moving the beakers of water and oil to the stands. Move the
thermometers into the liquids or onto the solids. Practice heating and cooling.
When you are ready to begin the assignment, move both beakers on top of the heating mantles, and place the
thermometers, which are located in the upper left corner of the screen, into the liquids. The arrow to the left of the
thermometer will turn the same color as the liquid when submerged.
Drag the bar on the heating mantle and hold it at maximum heat until the red liquid in the thermometer is at the
top of the thermometer. In the boxes below, insert a screenshot of the beakers when they are at the maximum
temperature (red liquid in the thermometer is at the top of the thermometer). This is the “Hot water & oil.” You can
take screenshots by selecting the three vertical dots in the bottom right hand corner of the simulation screen and
then selecting “Screenshot.” A screenshot will be downloaded to your browser which you can save to your
computer.
Repeat this procedure but cool both beakers with the liquids by dragging the bar to cool and holding at maximum
cool until the liquid in the thermometer is at the bottom of the thermometer. Insert a screenshot of the “cool water
& oil.”
8) Take the beakers of liquids off the heating mantles and replace with the iron and brick. Move the thermometers to
the solid objects you are about to heat & cool.
9) Drag the bar on the heating mantle and hold it at maximum heat until the red liquid in the thermometer is at the
top of the thermometer. In the boxes below, insert a screenshot of the blocks when they are at the maximum
temperature (red liquid in the thermometer is at the top of the thermometer). This is the “Hot iron & brick blocks.”
10) Repeat this procedure but cool both blocks by dragging the bar to cool and holding at maximum cool until the
liquid in the thermometer is at the bottom of the thermometer. Insert a screenshot of the “cool iron & brick blocks.”

Part I:
1.
Hot Water & Oil
Cool Water & Oil
Hot Iron & Brick Blocks
Cool Iron & Brick Blocks
2.
At the molecular level, what form of energy do the molecules have?
3.
Heat up the brick and the iron to the same temperature. What differences do you notice?
Brick
Iron
4.
What does temperature measure? Support your answer with evidence from the simulation.
5.
Put a hot object into cold water. Take a screenshot and then explain what happens to the energy in each of the
stages. The diagram below is to give you a visual of what you should do. You should insert your screenshot &
explanation below this diagram.
6.
When and why does the process in 5 stop?
