The most energy Essay Example for Free

The most energy Essay Make sure its on the same flame all the time.   Make sure its the same amount of water all the time (20cm )   Make sure the Bunsen burner isnt too close to the test tube. Stir the water before taking the temperature.   Always weigh the crisp each time. RISK MINIMISING RISK Burning bench Use bench mats Tripping over stools or bags Stools and bags under benches Burning of hair Tie hair back Damaging of eyes Wear safety goggles Paper setting alight Tidy desks, clear of paper Burning or scolding hands Use tongs and set Bunsen burner to safety flame Accuracy and reliability This experiment is fairly accurate but not 100%. To prove the reliability of the experiment we decided to do 3 trials of each crisp type and set to an average. The reliability is good also if you make sure its a fair test. Results 1. Crisp type: Cheese and Onion French Fries. Results 3. Crisp type: Ready Salted Hula Hoops Trial no: 1 2 3 Average Mass of crisps (g) 0. These results look fairly reliable, the mass varies quite a lot between each crisp type as the Peak potatoes crisps on average are 0. 26g and the Walkers Lite are 0. 75g. The temperature increase has turned out very high compared to the other crisps, but this is probably because it has a higher fat content than the rest. The equation to find out how much ENERGY RELEASED from 100g of crisp. Mass of water (20cm ) X Temp difference X 4. 2 = Energy Released J/_______g J/________g mass of crisp (J/1g) X 100 (J/100g) 1000 (KJ/100g) = Energy Released from 100g of crisp KJ/100g. Average Energy Released per 100g French Fries: 1 7 Peak Potato: 56 + 115. 2 +90 KJ/100g = 261. 2 3 = 87. 1 Ready Salted Walkers: 240 + 247. 8 +108. 6 KJ/100g = 198. 8 3 = 198. 5 Hula Hoops: 36 French Fries Peak Potatoes Hula Hoops Walkers Lite 144. 7 KJ/100g 87. 1 KJ/100g 348. 7 KJ/100g 198. 5 KJ/100g Analysing and Evaluating my results. There is no pattern in my graph that I can see, the highest average energy released is Hula Hoops, and this is strange because the highest fat content is Walkers with 34g whereas Hula Hoops is only 28. 1g. I predicted that the crisps with the highest fat content will release the most energy, but this is not true because of my anomalous results. My method could have been a bit better by being more accurate. If I was to do this again I would redo the Hula Hoops and Walker Lite to make sure they are completely accurate. Im not sure how theses anomalous results occurred it could be my calculations or results that are inaccurate. I could extend this investigation by looking at different the sizes of the crisps and how much energy they release or a different food similar to crisps. From my results and the manufacturers results I can see there is a big difference this is because the manufacturer uses a calorimeter. The body uses energy to conduct vital functions and maintain itself at a constant temperature. By using a Calorimeter scientists have established the amounts of energy in the bodys fuels-carbohydrates, fats, and proteins. When you read the nutritional information on the foods packets you buy, the amount of calories in the food are stated. This is not the total energy in the food, but the amount of biologically available calories, i. e. the amount of energy in the food that your body can metabolise. A calorimeter of the type invented by Rubner is used to obtain these measurements. The manufacturer most likely used a calorimeter to measure the energy value in their crisps. This would have been tested many times under very controlled circumstances. In a calorimeter, all the heat given off by the food is transferred to a known quantity of water, which rises in temperature. It takes 4. 2 joules of heat to raise the temperature of 1g of water by 1oc. I think I have anomalous results because of the way I held the walkers crisp as it is the only odd one; I think that maybe where the tweezers were holding the crisp. The results on my graph are meant to go up in a straight line but it doesnt as the Walkers crisps result is out of place. From my results I can see my prediction is heading in the right way. The crisps with the highest fat content are Hula Hoops with 34g and I predicted that this would have the highest amount of released energy which would be true if my Walkers results were correct.

A Modern Grendel :: Literature, Beowulf

In the epic poem Beowulf, the monster Grendel is depicted as a villainous beast with an unquenchable thirst for human flesh and blood. Grendel, written by John Gardner, though, offers a more nuanced depiction of the beast by describing the events in Beowulf through Grendel's narration. Throughout the story, Grendel adopts various romantic characteristics and beliefs including isolation, individualism, and mysticism. These romantic characteristics, though, foster Grendel's murderous intentions and in turn gives him an anti-hero persona. Nearing the end of the novel, his romantic antihero trends transforms his life into a never ending limbo. His only salvation comes in the form of death. Grendel's' inevitable demise represents inescapable fate. Romanticism places a heavy focus on separation from society. In Gardner's novel, this romantic theme of isolation is echoed when Hrothgar's community rejects Grendel. Grendel, even before he discovers the humans, has always been in a sense alone. His mother is too inarticulate to be considered a truly fulfilling companion and the animals around him are too primitive to even communicate. The only creature that Grendel could ever truly bond with was the human race for they both shared the same language, and intellect. The humans, though, never embrace Grendel. The very first time Grendel attempts communicating with the humans, when he "staggered out into the open and up toward the hall...groaning out, 'Mercy !Peace!'"(51), results with him being nearly killed with spears, arrows, and swords. Humanity, his closest peer, rejects Grendel and forces the beast to live the rest of his life in isolation. But unlike in romanticism, in which isolation is viewed positively, Grendel's lonelines s is shown to be more of a curse than as a boon. Grendel despises his loneliness and it turns him into a spiteful creature whose goal is to destroy Hrothgar. This dedication, fed by a hatred to his loneliness, results in Grendel's transition into an anti-hero. Rather than living peacefully in nature, Grendel chooses to be consumed by the romantic idea that society, specifically Hrothgar's society, is evil, corruptive, and destructive. For Grendel, he comes to the self-realization that he is, "Grendel, Ruiner of mead halls, Wrecker of Kings"(80), and it his duty and fate to kill and eat Hrothgar's citizens. Isolation is not the only aspect of a romantic hero. Individualism and a person's ability to choose their own actions also play an important part. In Gardner's novel, Grendel acts on his own whim and does not follow the advice that others give him.

Halo †Humanities Essay

Follow Nobody hates writing papers as much as college instructors hate grading papers (and no, having a robot do it is not the answer). Students of the world: You think it wastes 45 minutes of your sexting time to pluck out three quotes from The Sun Also Rises, summarize the same four plot points 50 times until you hit Page 5, and then crap out a two-sentence conclusion? It wastes 15 hours of my time to mark up my students’ flaccid theses and non sequitur textual â€Å"evidence,† not to mention abuse of the comma that should be punishable by some sort of law—all so that you can take a cursory glance at the grade and then chuck the paper forever. What’s more, if your average college-goer does manage to read through her professor’s comments, she will likely view them as a grievous insult to her entire person, abject proof of how this cruel, unfeeling instructor hates her. That sliver of the student population that actually reads comments and wants to discuss them? They’re kids whose papers are good to begin with, and often obsessed with their GPAs. I guarantee you that every professor you know has given an A to a B paper just to keep a grade-grubber off her junk. (Not talking to you, current students! You’re all magnificent, and going to be president someday. Please do not email me. ) Oh, â€Å"attitudes about cultures have changed over time†? I’m so glad you let me know. When I was growing up, my mother—who, like me, was a â€Å"contingent† professor—would sequester herself for days to grade, emerging Medusa-haired and demanding of sympathy. But the older I got, the more that sympathy dissipated: â€Å"If you hate grading papers so much,† I’d say, â€Å"there’s an easy solution for that. † My mother, not to be trifled with when righteously indignant (that favored state of the professoriate), would snap: â€Å"It’s an English class. I can’t not assign papers. † Mom, friends, educators, students: We don’t have to assign papers, and we should stop. We need to admit that the required-course college essay is a failure. The baccalaureate is the new high-school diploma: abjectly necessary for any decent job in the cosmos. As such, students (and their parents) view college as professional training, an unpleasant necessity en route to that all-important â€Å"piece of paper. † Today’s vocationally minded students view World Lit 101 as forced labor, an utter waste of their time that deserves neither engagement nor effort. So you know what else is a waste of time? Grading these students’ effing papers. It’s time to declare unconditional defeat. Most students enter college barely able to string three sentences together—and they leave it that way, too. With protracted effort and a rhapsodically engaged instructor, some may learn to craft a clunky but competent essay somewhere along the way. But who cares? My fellow humanists insist valiantly that (among other more elevated reasons) writing humanities papers leads to the crafting of sharp argumentative skills, and thus a lifetime of success in a number of fields in which we have no relevant experience. But my friends who actually work in such fields assure me that most of their colleagues are borderline-illiterate. After all, Mark Zuckerberg’s pre-Facebook Friendster profile bragged â€Å"i don’t read† (sic), and look at him. Of course it would be better for humanity if college in the United States actually required a semblance of adult writing competency. But I have tried everything. I held a workshop dedicated to avoiding vague introductions (â€Å"The idea and concept of the duality of sin and righteousness has been at the forefront of our understanding of important concepts since the beginning of time.†) The result was papers that started with two incoherent sentences that had nothing to do with each other. I tried removing the introduction and conclusion altogether, and asking for a three-paragraph miniessay with a specific argument—what I got read like One Direction fan fiction. 200500899-001 The sliver of the student population that actually reads comments and wants to discuss them? They’re kids whose papers are good to begin with, and often obsessed with GPAs. Photo by Nick White / Thinkstock  I’ve graded drafts and assigned rewrites, and that helps the good students get better, but the bad students, the ones I’m trying to help, just fail to turn in any drafts at all. Meanwhile, I come up for air and realize that with all this extra grading, I’m making 75 cents an hour. I’m not calling for the end of all papers—just the end of papers in required courses. Some students actually like writing, and let those blessed young souls be English majors, and expound on George Eliot and Virginia Woolf to their hearts’ content, and grow up to become writers, huzzah. But for the common good, leave everyone else out of it. Instead of essays, required humanities courses (which I support, for all the reasons William Cronon, Martha Nussbaum, and Paulo Freire give) should return to old-school, hardcore exams, written and oral. You cannot bullshit a line-ID. Nor can you get away with only having read one page of the book when your professor is staring you down with a serious question. And best of all, oral exams barely need grading: If you don’t know what you’re talking about, it is immediately and readily manifest (not to mention, it’s profoundly schadenfroh when a student has to look me in the face and admit he’s done no work). Plus, replacing papers with rigorous, old-school, St. John’s-style tribulations also addresses an issue humanities-haters love to belabor: Paper-grading is so subjective, and paper-writing so easy to fake, that this gives the humanities their unfortunate reputation as imprecise, feelings-centered disciplines where there are â€Å"no right answers. † So let’s start requiring some right answers. Sure, this quashes the shallow pretense of expecting undergraduates to engage in thoughtful analysis, but they have already proven that they will go to any lengths to avoid doing this. Call me a defeatist, but honestly I’d be happy if a plurality of American college students could discern even the skeletal plot of anything they were assigned. With more exams and no papers, they’ll at least have a shot at retaining, just for a short while, the basic facts of some of the greatest stories ever recorded. In that short while, they may even develop the tiniest inkling of what Martha Nussbaum calls â€Å"sympathetic imagination†Ã¢â‚¬â€the cultivation of our own humanity, and something that unfolds when we’re touched by stories of people who are very much unlike us. And that, frankly, is more than any essay will ever do for them.
