Question

States of Matter Lab:1.  Use the PheT simulation found at:https:phet.colorado.edu/sims/html/states-of-mattelatest/states-of-matter_en.html2.  Select the simulation labeled “Intro”.  Click on each of the labels (solid, liquid, gas) to familiarize yourself with what each looks like in the simulation.  Then click the reset button.3.  The little blue circles represent the molecules of Neon in the container.  Use the temperature control underneath the container to add heat to the neon in the container.  Describe carefully what happens to the molecules.  What state of matter does this represent?4.  Now apply the ice to cool the Neon in the container.  Describe carefully what happens to the molecules.  What state of matter does this represent?5.  Repeat this process with Neon, Argon, Oxygen, and Water, noting the temperatures for each.  Complete the table below with your findings.  (Note:  for the solid state, record the temperature at which the majority of the atoms or molecules are in the solid state (they won’t necessarily all be in the solid state;  do the same for the gaseous and liquid states.)      Substance    Solid Temperature    Liquid Temperature    Gas Temperature    Neon                Argon                Oxygen                Wate            6.  Which substance becomes a gas at the lowest temperature?  At the highest temperature?  Which becomes a solid at the lowest temperature?  The highest temperature?7.  What is different about oxygen and water compared to Argon and Neon?  How does this affect the temperatures at which their phase changes occur?   (Hint:  look carefully at the circles…)8. Now select the simulation labeled “Phase Changes”.  This simulation includes a phase diagram like the ones in your text in chapter 14.  Select water, and apply heat to the container.  Describe how the phase diagram relates to what you see in the simulation.9.  Now apply ice to the container and again describe how the phase diagram relates to what you see in the simulation.10.  Summarize what you have learned by doing this lab (300 words minimum).

1.  Use the PheT simulation found at:
https://phet.colorado.edu/sims/html/states-of-matter/latest/states-of-matter_en.html
2.  Select the simulation labeled “Intro”.  Click on each of the labels (solid, liquid, gas) to familiarize yourself with what each looks like in the simulation.  Then click the reset button.
3.  The little blue circles represent the molecules of Neon in the container.  Use the temperature control underneath the container to add heat to the neon in the container.  Describe carefully what happens to the molecules.  What state of matter does this represent?
When we heat the molecules become more scattered than was before.  This means the solid state is slowly reducing with molecules going away from each other.  Gases increase their volume while heating and thus molecules become more scattered occupying more space.  Neon is gas here and when heated spreads over more. i.e. when heated gas molecules vibrate more and more thus increasing volume and pressure.
4.  Now apply the ice to cool the Neon in the container.  Describe carefully what happens to the molecules.  What state of matter does this represent?
When cooling takes place molecules move slowly i.e. vibration is now very slower thus decreasing the volume also the gas occupied.
Gases when cooled become denser occupying less volume and molecules less vibrate.
5.  Repeat this process with Neon, Argon, Oxygen, and Water, noting the temperatures for each.  Complete the table below with your findings.  (Note:  for the solid state,
