On January 18, 2015, the New England Patriots and the Indianapolis Colts played in the AFC Championship game in a chilly temperature of 51°F. The Patriots were accused of cheating when, at half time, 11 of their 12 game balls were found to be two pounds psi less than the regulation size of 12.5 to 13.5 psi. Although the balls are gauged 2 hours and 15 minutes prior to the game, they are returned to the teams before the game started. Based on extensive research and data, the Patriots’ balls were tampered with prior to the game. Objects with gaseous interiors have a tendency to decrease in pressure when exposed to cold temperatures but the decrease will only be minor.
When you collect the gas through the eudiometer, the water inside the eudiometer gets displaced, evaporating until the pressure of the water outside is equal to the pressure inside. To correctly find the pressure of the gas, the pressure of the water vapor must be subtracted, as the two are mixed together. What is the limiting reactant for the reaction? What is the experimental evidence that you are basing it on?
The liquid contained inside has no choice but to move upward and downward as the temperature creates the substances to grow or shrink. 6. Thermometers have a large bulb and a narrow tube to accentuate the change in volume. 1.
Stoichiometry is a method used in chemistry that involves using relationships between reactants and products in a chemical reaction, to determine a desired quantitative data. The purpose of the lab was to devise a method to determine the percent composition of NaHCO3 in an unknown mixture of compounds NaHCO3 and Na2CO. Heating the mixture of these two compounds will cause a decomposition reaction. Solid NaHCO3 chemically decomposes into gaseous carbon dioxide and water, via the following reaction: 2NaHCO3(s) Na2CO3(s) + H2O(g) + CO2(g). The decomposition reaction was performed in a crucible and heated with a Bunsen burner.
Oxygen was being consumed and carbon dioxide was being released because the water level in test tube “G” continued to
The writer of This Way for the Gas, Ladies and Gentlemen, is Tadeusz Borowski. He was a polish writer, who was a survivalist of the Holocaust. Tadeusz wrote most of his books about his challenges and issues he had to overcome during the Holocaust. Although, Tadeusz committed suicide he left behind a great read for many of us to understand an insight on the Holocaust. The theme of, This Way for the Gas Ladies and Gentlemen, reveals the emotional, physical, and territorial impact that hunger (and other items) has on humans.
In the poem “Treblinka Gas Chamber”, by Phyllis Webb and in the TRC’s “The History”, both texts share a common theme of inhumane treatment towards children within certain cultural and ethnical groups. While the two authors explore distinct historical contexts, both texts are centred on racial segregation with nationalistic motives. Phyllis Webb appeals to a logos strategy through the use of allusion. In her poem, “Treblinka Gas Chamber”, Webb presents fictional and historical examples to display her knowledge and establish her credibility.
Why did you go after to find Sasha? I went after to find Sasha because she is my true love. Also, I went after to find her because when we were in the infected zone together she saved my life, when the jocks were after me. Sasha also saved my life by helping me into a gang so I had a place to stay and food to eat. Were you ever scared looking for Sasha in the infected zone?
In scientific writing being able to identify and use audience, context, and purpose correctly in scientific writing is very helpful in providing what the specific paper will be about (context), who it is targeted toward (audience), and what is the reasoning behind the given section of a reading (purpose). Aristotle was once quoted saying, “Rhetoric is the art of seeing, in any given case, the available means of persuasion.” Being able to dissect someone's stance on an argument is a very important skill to have. Just because someone is able to publish a paper on a certain topic does not mean you should immediately accept everything in that paper. In the scientific journal titled, “The Delphic Oracle:

Freezing- Pose a Question: How does the amount of dry ice effect how much the balloon grows? Hypothesis: We think that the more Dry Ice we put in the balloon will make it bigger because as their is more dry ice there will be more gas and carbon dioxide exerted by the dry ice when you put water over it. Design an Experiment: Materials list :- Dry Ice Empty water bottle Water A balloon (preferably colorless) Metric ruler Procedure :-
Place the the beaker onto a hot plate that is on a low heat setting (about setting 3). Every 5 minutes for 20 minutes, measure the circumference of the balloon and record it in Data Table A. You can measure the circumference of the balloon by looping a piece of string around it then using a ruler to measure the string’s length. Record the data in the data
The Conservation of Energy lab performed in class measured physical characteristics, the actual conservation of energy in idea circumstances, and the energy that is lost in the bounce of a variety of balls. The objects that were measured included a golf ball, ping pong ball, racquet ball, billiard ball, marble, and tennis ball. As a group it was required to write a hypothesis related to measurements of mass/weight, energy lost and energy change from the bounce. The group predicted that the billiard ball would have the most mass, weight, and density, while the tennis ball would have the most volume. Also was predicted that the ping pong ball would loose the most energy, and while performing the experiment the higher the top of the drop was
The value of the properties determine the state of the gas, and these values are related to one another (NASA 2015). Robert Boyle was a scientist who observed the relationship between pressure and volume. He came to the conclusion that the relationship between pressure and volume is inversely proportional when held at a constant temperature. The equation for Boyle's law is P1V1=P2V2, which states that as pressure increases volume decreases, and as volume increases pressure decreases. Boyle studied the pressure of air in a U shaped curve, which only worked if the temperature and moles remained constant.
