GAS

   In class, we were looking at different types of solid liquids or gases, and how energy(taking or adding heat) affects them. I specifically looked at Neon,Argon,Oxygen and Water. Water, as we all know is a liquid. Oxygen, is a gas(also something we breathe.) As I observed all different changes, I found similarities and some differences.

    When I tested the Neon, I first added heat and the particles went from together to spreading out and started moving. The movement was very different from the others, because the molecules started vibrating and then the edges started to flow off and suddenly everything.When I subcontracted heat, it looked as if the particles started joining and finally at 0 degrees it froze. Next was the Argon, when I added heat, the molecules moved much faster than in the Neon. Also, when I tested this one, first just some of the particles came of and the others traveled together but finally they went apart. On the other side, when I cooled the Argon, all the particles came together but slowly and formed a shape that again, froze at 0 degrees. Next, was the Oxygen. When I heated that, it took a longer while then others to let go of each other, but then they started moving really fays. ( The particles)When I cooled it, they would wiggle and as the others, stop. Last, was the Water. When water gets heated, it lets the particles go and they move around like crazy, really fast. Finally, by cooling water, the molecules get close and stop wiggling, this makes fro example ice.

After all, all the substance, froze when they were cooling at one point and all of them had free particles while they were heated. So, no matter if it is a solid, liquid or gas, they can be similar and help us learn.

Don't think it is over yet, we had a second part  to the experiment. In the second part, the bowl we worked with, had a thermometer, a finger holding down a lid, and a pump where you could add more molecules. I worked with the same substances. For Neon, I did a simple way, I didn't really work with the finger and the adder but I made the temperature be about 60 degrees and then I pushed the lid down, and the pressure was about 150. After, the lid blew up.When I cooled the Neon, I could push the lid as much as I wanted until I reached the substance and then eventually it blew up. When I tried this with Argon, i went to about 119 degrees and I could push the lid about 1/5 more than half.  Then, I made the temperature be 0degrees and I added about 31 particles and the temperature became about 8. In all of them though, when I started pushing, the particles started moving faster like they were in a hurry. Before last, I tried it out with Oxygen. The temperature was about 160 and the lid was able to go down about 1/5 of the cup. For the cold part, I added 5 pumps, and they molecules joined, they touched and then I touched it with the lid and finally BOM! Last, Water. my high temperature I choose was 392 degrees and I added about 3 pumps with particles. The water was the most resistant to the pressure. When I pushed the lid down. the particles went up and down until they went sailing up and the lid came off. For the cooling, my temperature was 0 degrees and I added 6 pumps of particles. It blew up when I touched it and so on....
So, now we are here, the end, I learned that pressure and gas can be pretty similar but have different potentials!
