This article was about the states of matter. This article focused on the “solid” state of matter. The reason I think this article focused of the solid state of matter is because of the subtopic names. Some of the subtopic names were, the solid state of matter, classification of solids, the nature of crystalline solids,metallic solids,molecular solids, covalent solids… That is some of the subtopics for only the first four pages and there is already that much talked about solids. This article was had a lot do with statistics/numbers also. There were a couple graphs and tables in the article and they had a lot of information on the states of matter especially solids. The article was also had the “equations of state” the equation is pV=nRT this Approximately correct for the of gases because the volumes consists almost entirely of empty space. This equation is used for gases only.This article was also about the differences of the differences of solids, liquids, and gases. The article gives reasons about how the three states of matter differ. One was is that gas is transparent and has no boundaries. Another one is that solids clearly possess a defined shape. And a third way the three states of matter differ is that solids have a conceivable shape. There are a lot more ways that the three states of matter differ but these are just a few examples. III. This article relates to what we are learning currently in physical science in many ways. We learned about the different states of matter earlier in the year and lots of things about them. We learned how the three states of matter are the same and are different. We learned about how the states of matter can be put back to their original forms and why they can’t at some points also. We have learned a lot about the states of matter this year and even last year But there is still a lot to learn about them.The reason I picked this article is because, I am very interested in the whole idea of “the state of matter.” I am interested in it because there are so many things that are different and similar to all of the different states of matter. I like how you are able to do so many things with all three states of matter also. I think it’s insane how there are so different types of objects/materials that can tie into the states of matter. Like all liquids, solids, and gases can be involved the the subject ” the state of matter.”V. Three new vocabulary words that I learned were…Viscosity- The state of being thick, sticky, and semifluid inconsistency, due to internal friction.Cohesiveness- The quality of forming a united whole.Surface tension- The tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
