Behavior of Gases Essay Example for Free

Behavior of Gases Essay Introduction: In this experiment, the problem trying to be solved is what gas laws are being used when the pressure, temperature, and volume are being measured. The three gas laws are Boyle’s Law, Charle’s Law, and Gay-Lussac’s Law. The Boyle’s Law is when volume and pressure are being compared. Pressure and volume are inversely proportional, because when pressure goes up, volume goes down. The Charle’s Law is when volume and temperature are compared. Volume and temperature are also inversely proportional as well. Lastly, Gay-Lussac’s Law is when pressure and temperature are compared. Pressure and temperature are directly proportional; therefore when pressure goes up, temperature also goes up. The formulas are as follows: Boyle’s Law: P2 P1 = P2 V2 Charle’s Law: V1/T1 = V2/T2 Gay-Lussac’s Law: P1/T1 = P2/T2 Hypothesis: If volume, temperature, and pressure are measured, they will follow the laws and fit under Boyle’s, Charle’s, or Gay-Lussac’s law. Expected Results: It should be expected that when volume and pressure are measured, pressure will go up and volume will go down. When volume and temperature are compared, volume will go up and temperature will go down. Lastly, when pressure andtemperature are measured, pressure will go up as temperature goes up. Experimental Procedure: Part I Connect a 20mL syringe to a LabQuest Select: File New Then, Mode: Change to Events with Entry Next, Enter Name as Volume Enter Units as mL Select OK Start at 10mL on the syringe and wait for the reading to Select Keep Keep at least 6 data points (any of your choice) Only pull the syringe out (making the mL readings higher each time) Stop the Data Collection and view the graph and points Record Part II Place an Erlenmeyer flask in a beaker big enough to fit the flask Connect a temperature apparatus to the Lab Quest and place probe in beaker Then connect the pressure tube to the Lab Quest in channel 2 and connect the other end of the tube with the rubber stopper to the Erlenmeyer flask Select: File New Then Mode: Change to Selected Events Exit In sensors menu, change units to Kelvin Tap graph X-axis: chose temperature Place faucet, room temperature water in the beaker Select Keep Place ice in the beaker Select Keep Place room temperature water in the beaker again and place on a hot plate Wait for the water to boil Place temperature probe and Erlenmeyer flask back in beaker Select Keep Record result from graph and chart Results: VOLUME (mL) PRESSURE 10 103. 27 12 87. 6 14 76. 14 16 67. 5 18 60. 96 20 55. 15 This data and chart is comparing volume and pressure. The graph represents the Boyle’s Law because as the pressure is going up the volume is going down. TYPE OF WATER TEMPERATURE (K) PRESSURE Normal 102. 8 295 Ice 98. 29 275. 4 Boiling 122. 31 357. 4 This data and chart is comparing temperature and pressure. The graph represents Gay-Lussac’s Law because as temperature goes up, pressure goes up as well. Discussion: This experiment went extremely smooth. The data was easy to collect as long as you kept the Lab Quest and tools stable to ensure for accurate readings for temperature, pressure, and volume. The graphs and data easily coincided correctly with the theories of the gas laws, as was shown accessibly once the graphs were made. Although the data coincided with the theories correctly, the temperature readings for freezing and boiling may have not been completely accurate because the temperatures of the water was not measured accurately for correct boiling and freezing temperatures, but recorded solely for the theories and to prove them. Overall, the experiment held up well and the hypothesis and theories were proven to be correct.

Cahills How The Irish Saved Civilization Essay -- essays research pape

Cahill's How the Irish Saved Civilization Thomas Cahill opens his story describing Rome's fall, â€Å"For as the Roman Empire fell, as all through Europe matted, unwashed barbarians descended on the Roman cities, looting artifacts and burning books, the Irish who were just learning to read and write, took up the just labor of copying all of western literature - everything they could get their hands on. These scribes then served as conduits through which Greco-Roman and Judeo-Christian cultures were transmitted to the tribes of Europe, newly settled amid the rubble and ruined vineyards of the civilization they had overwhelmed.† (Cahill, p.3) The theme of this book is that the scribes did something unique, they saved civilization, not the masses of people, but literature, the content of â€Å"classical civilization.† (Cahill, p. 58) One reads of the time from Rome's fall to medieval times learning through the stories of the characters, most notable Augustine and Patrick.   Ã‚  Ã‚  Ã‚  Ã‚  Augustine, his faith based on Roman Chrisitanity, â€Å"looked into his own heart and found the anguish of each individual.† (Cahill, p. 115) Patrick, the slave turned Christian, escapes only to return to convert the Irish. He was the first missionary to the barbarians beyond Greco-Roman law â€Å"who looked into the hearts of others.† (Cahill, p. 115)   Ã‚  Ã‚  Ã‚  Ã‚  Cahill notes Ireland is the only land where Christianity is introduced without violence - there were no murdered Irish...

In Mary Wollstonecraft’s novel Frankenstein, she displays how Dr. Victor Frankenstein and the Monster experience a variety of emotions , feelings of Shame, Happiness, and Pain are all felt by the two main characters as they venture throughout the story. Victor Frankenstein and the monster both experience shame. For example when Victor illustrates shame is when he decides to create an animated monster but was cared of his own creation, once his monster sprung to life. Victor saw the monsters pale yellow skin and monstrous eight feet high and was disgusted by it and was shamed of what he created. He abandoned his creation hoping it would disappear. Another example of when Victor shows shame was when Victor’s life was threatened by the monster because the monster wanted a female friend and forced Victor to create another monster. Victor starts to build on the monster in a remote island in Scotland but is ashamed his own selfishness; building another monster to save imself when the monster could case destruction and death on other humans Just like how his original creation killed his brother, William Frankenstein died. In anger at himself he tears up his half created monster. The monster also shows shame. The monster shows shame when he looks into the water of the pond and sees his own reflection and exclaims in agony â€Å"Why did you form a monster so hideous† (93). The monster realizes that he is hideous and is ashamed of himself. He is then struck with anger and seeks revenge on Victor for giving him a repulsive face. Another example when he demonstrates shame was when he passed by the town and the people would shriek and hit him. Learning from that experience he did not go into town again and became ashamed of himself so he hid in the forest, sheltering himself in the dirt hovel that was next to the cottage of the DeLacey family. Victor and the monster also experienced happiness but it doesn’t last long. The first time Victor was ever truly happy was when he was a child and he was also content when he was with his girlfriend and soon to be wife, Elizabeth Lavenza. Another moment of happiness for Victor was when he finished his creation that he has been working on for two years. He describes it as â€Å"Beautiful! -Great God!†¦ his teeth of pearly whiteness†¦ † (35). The monster shows happiness too when he is around nature, he appreciates and is happy with nature because nature is the only thing that doesn’t make insult him for his looks. His was also blissful when he demanded Victor to make him a mate and Victor agreed. Victor and the monster additionally feel pain; emotionally and physically. Victor first feels emotional pain when his mom and his best friend Henry died. Victor undergoes emotional pain when Justine was executed and Victor becomes increasingly melancholy. He considers suicide but restrains himself by thinking of Elizabeth and his father. Another example is when Felix DeLacey hits the monster Molently with a stick† (97) in fear that the monster will harm his family . The monster suffers pain when he is like a newborn, still clue less to the new world he is in and decides to touch he tire that is warm and soothing. He soon discovers the tlames could burn his hands. The monster also goes through emotional pain when Victor Frankenstein dies and the monster cries for him because the monster has no purpose in life and is emotionally frustrated. Both characters experience a series of emotions and have each changed emotions in comparison this are very similar yet they are very different. As both characters experienced pain, happiness, and shame it greatly affected their lives and how they behaved to each other.

Making People Perfect - 568 Words

If everyone is perfect, then won’t perfect lose its meaning? Or would perfect only be for the wealthy? Scientists are now taking eggs from women and are changing the genes so they can decide what hair color, eye color, and skin color they want their child to have. They may also do it if their genes have a genetic disease like, higher risk of heart attacks or strokes, autism, cancer and much more. But at what risk? Overpopulation, dominating groups, decided futures, preventing the less fortunate or naturally born from progressing and/or unforeseen consequences. We should not design babies because if we do then if will overpopulate and sooner or later if the earth is overpopulated we may have a shortage of food or water. Then what? Some of the advantages of designing babies is the freedom of choice. The freedom of choice argument is letting a woman and man choose if they want a genetically modified baby. This is an advantage because it is pro freedom of choice. And that if your family has a genetically transferred disease, because then you could prevent your kid from having said disease or diseases (Parry). But as well as advantages there are disadvantages. For example, history has shown that in the 1940s, the Nazis tried to design the human race, just like they are trying to design the next generations of people (Keim).
