Separation of Online Communities :: Argumentative Persuasive Papers

Separation of Online Communities On January 10 of 2003, I struggled with an inorganic chemistry homework problem on entropy before the night of my exam. I logged on to an inorganic chemistry forum. This forum is similar to the structure of a classroom. The forum is popular among two types of members, instructors and students. The students post their homework, and the instructors answer the questions posted by the students. The average number of posts in that site is 30 per day. The forum is extremely popular and continuously filled with questions and requests for help with homework. I was hoping that someone knew the answer to my question and would respond to me before my exam. I therefore posted: â€Å"Rank the following element in decrease entropy, Al(s), Ba(s), Hg (l), H2 (g), HBr (g), Thanks for your help I would like to know the answer of this A.S.A.P because my exam is tomorrow morning.† Within an hour I received this response from Professor Helmenstine, the administrator of the site, also a professor in chemistry department: The order should be HBr (g), H2 (g), Hg (l), Ba(s), Al(s). An ordered state has a low probability of occurring and low entropy. A disordered state has a high probability of occurring and high entropy. Gas has the highest entropy because it is more disordered than any other element. And solid is in the most ordered state; therefore it has the lowest entropy. I know this is the first time you posted but I must inform you that integrity is essential in this site’s posting. I recommend you follow your school’s honor codes and not attempt to get any unauthorized aid from this site. Please check out this site’s regulation page and please follow the rules of this site. I hope that I helped and good luck on your exam.† (Helmenstine) I was delighted that I was able to receive help from a forum. After all, the online communities are similar to what Rheingold stated in his article â€Å"Virtual Community.† â€Å"In the summer of 1986, my then-two-year-old daughter picked up a tick. There was this blood-bloated thing suck on our baby’s scalp, and we weren’t quiet sure how to go about getting it off.
