Review:
Kinetic energy (KE) is the energy of motion.
Potential energy (PE) is the energy of position.
What property of a substance corresponds to the average KE of its particles? Temperature What property of a substance corresponds to the average PE of its particles? Phase List the three common states of matter in order of highest potential to lowest. Gas, liquid & solid. e-Lab:

Open PhET simulation States of Matter.
The beginning of the lab starts with Neon in a solid state at 13 K. (Kelvin (K) is a unit of temperature like Celsius and Fahrenheit). You can heat or cool the substances in the container by sliding the bar on the bucket to Heat (for fire) or Cool (for ice). Slide the bar to Cool and cool the neon to 0 K (this will take a while). The atoms are …

not moving.
sliding past each other.
moving independently around the container.
Is this physically possible (think Third Law of Thermodynamics)? No Go up to the tab that says “teacher” and change the temperature scale from Kelvin to Celsius. According to this 0 K = 273 C. Change the scale back to Kelvin. Notice the pattern of the atoms relative to each other. This pattern can best be described as rectangular

hexagonal
octagonal
amorphous (random or no pattern)
This pattern is the solid Neon's crystalline structure.
Click on the “Solid” button on the right of the page. This puts the Neon's temperature back to 13 K. What is this temperature in Celsius? -260 C The atoms are …
not moving.
sliding past each other.
moving independently around the container.
Are the atoms still in their crystalline pattern even though they're moving? Yes Heat the solid Neon to 20 K. What is this temperature...
