GAS LAWSKINETIC ENERGY/ GRAHAMS LAW LABPurposeTo observe how masses of atoms and molecules make a motion their rate of diffusion, and explain our observations in terms of mass, velocity, kinetic energy and temperature.Warm-up Question1.     What is the definition of temperature?Temperature is a measure of the average Kinetic Energy of the particles composition a material.2.     What is the definition of diffusion?Diffusion is a spontaneous spreading of particles until they are uniformly distributed in their container.3.     If we increase the temperature of sample of vaunt, then what about the gas molecules will have to change?The gas molecules would begin to increase in speed since the temperature would increase.4.     The element iodine (I2) diffuses more slowly than ethanol (CH3CH2CH2OH). Why is this? unity is heavier in atomic mass then ethanol, slowing down its process to diffuse. Iodine weighs 2 53.6u while ethanol weighs 60.03u, giving ethanol a faster diffusions rate. map A1.     Obtain a glass tube and wash it with water. Dry the outside of the tube with a paper towel. Next, squirt some acetone into the tube. A small amount is all that is needed. Then dry the inside of the tube by passing air through the tube (use a fan, the window, blow through it, etc.)2.     Use chalk to label one end of your lab station, "HC1," and the other end, "NH3."3.     Lay the glass tube on the slacken and place the thermometer on the table next to the tube.4.     CATION THE NH3 AND THE HCI ARE IN VERY CONCENTRATED FORMS. DO NOT ALLOW EITHER CHEMICAL TO COME INTO CONTACT WITH YOUR SKIN. IF THE NH3 OR HCl SPILLS, GET A DAMP PAPER TOWEL AND CLEAN IT UP IMMEDIATELY5.     Obtain 1 small bottle of HCI and 1 small bottle of NH3. Place to each one bottle in their respective ends of t he lab table. Obtain forceps, label them, "HC1" or NH3"with tape, and place them at their respective end of the lab table.6.     Record the temperature of the air some the tube in the data table.7.     Separate the cotton ball into pieces small enough to stuff into the ends of the glass tube. Do not put them into the tube yet. 8.      eyepatch holding the cotton ball with the forceps, place 4 drops of HCl or NH3 (whichever corresponds to the label on the forceps).9.     Repeat step 8 with the other chemical. You should now have ii small cotton balls, one with 7 drops of HCI, one with 7 drops of NH3. Keep them at their respective ends of the lab station.

For Their Rights as Citizens :: essays papers

For Their Rights as CitizensDuring the Civil War, almost 200,000 African Americans fought alongside ashenpeople. What did these African Americans compact for? Some fought for the freedom ofothers of their kind. While others fought for equality in the eyes of white people. Even some fought for revenge against the Southern way of life. But what I debate that they fought for was their rights as citizens. They wanted to be treated as Citizens of the United States of America, and have all of the privileges endowed to citizens.If we press out to maintain a republican Government, we want Republican privileges.....all we ask is the proper enjoyment of the rights of citizenship, p205. This tells me that the African Americans were thinking of their rights of citizenship before the war had concluded. To them, being a citizen of the United States meant that they coulddo what ever they wanted to do. They could pursue dreams they had to go visiteverywhere and anywhere in this country freely. Nobody would be holding them down orselling off their children anymore. They would no longer be automatons, they would havea say in what they wanted to accomplish in life, from banking to farming, to being landowners themselves.The African Americans also wanted to demonstrate that they were willing to fightfor their rights. Sergeant Charles Singer wrote, show the whole world that we are willing to fight for our rights... p.215. This shows that they wanted to prove that they were willing to die for those rights allotted to citizens. Let us by a common cause now made holy by our blood, raise ourselves from the mire, p.216. To me this shows the willingness of the African Americans to join together fight for a cause, and non fear death. Because in the end, they would earn citizenship and all of its benefits. This is a goodreason to fight, earn freedom from oppression, and be given the rights allotted to allcitizens.Some engagement under the banner of citizenship and it s rights, believed that theydisserved the same rights as the white people. ...I am not willing to fight for anything less that the white man fights for.......Give me my rights, the rights that this Government owes me, the same rights that the white man has, p.208. This tells me that the African Americans wanted no less than what the white people already had.
