The Cold Equations

constricts. The gas then springs up when the ball becomes its usual shape, causing the tennis ball to bounce up. The height of a tennis ball’s bounce is determined by the pressure of the gas in the ball’s core. Pressure of a gas can be found with this equation: pressure =density × temperature × constant At a higher temperature, there is more pressure (if there isn’t a single change in density and constant); at a lower temperature, there will be less pressure. When temperature rises, the ball’s gas molecules

Katelyn Cassidy PHI 101 The Cold Equation written by Tom Godwin is a science fiction short story that raises issues in philosophy. The story is about a girl named Marilyn that sneaks on to an EDS, a little ship carrying fever serum to six men stationed on a planet Woden. Marilyn’s brother had been one of the six men stationed there and she wanted to see him because it had been ten years since she had last seen him. Marilyn was scheduled to take a ship to the planet Mirmir where she would see her

project, we analyzed cyclical steam injections in a heavy oil reservoir using reservoir simulations. We began the project as though we had been contracted to analyze a cyclical steam injection project in a pay-zone similar to the Clearwater formation in Cold Lake, Alberta. In this heavy, dead oil reservoir the facilities, injectors, and producer are already set up in the field with a seven spot orientation. The company wants further analysis on the project once the market declined, requesting reservoir

will result with no broken beakers. Results: Discussion: The chemical reaction we investigated was between hydrochloric acid and calcium carbonate. The equation used to describe this reaction is HCl +CaCo3 -> Ca Cl+ H2. It can be seen that the hydrochloric acid and calcium carbonate are the reactants in this equation and this forms the product calcium chloride and

Although outer space and planet Earth are two very different places, their laws can cause similar problems for drastically different people. Guy Montag, from Fahrenheit 451, written by Ray Bradbury, and Barton, from “Cold Equations”, written by Tom Godwin, are similar in many ways. Both men were significantly impacted by the words of a young girl in their lives. Both men also changed their views on the laws throughout the progression of the story. However, Guy Montag was able to have success in changing

1. It is important to include a control group whenever possible because it makes our data more accurate and strengthens its validity. The purpose of a control group is to observe any discrepancies that occurs between it and the other groups tested, thus helping display the effectiveness or usefulness of the treatment or whatever being tested. If an experiment does not have a control there is no benchmark for the results to be compared to or associated with, which will inevitably lead to the results

Introduction: The purpose of this experiment was to examine the relationship between heat transfer, temperature, and specific heat capacity of water and a metal. Prior to beginning the experiment, it was known that specific heat is the amount of heat needed to raise the temperature of a given sample of substance one degree Celsius, and specific heat capacity is amount of heat needed to raise temperature of one kilogram of substance one degree Celsius. The formula to solve for specific heat capacity

Add a single serving of cold water to the plastic cup B, stir and taste then record your data. Step five, with the muffin cup labeled “baking soda” add a measured amount of baking soda (1-5 grams) to the plastic cup C. Add a single serving of cold water to the plastic cup C, stir and taste then record your data. On step six, measure the amount of baking soda and citric acid (1-5 grams)

coefficients of the balanced chemical equation, to determine measurements such as the excess and limiting reactants. The chemical equation for this lab was NaHCO3(s) + HCl(ag) NaCl(s) + H2O(l) + CO2(g) and in the end of the lab the H2O and CO2 were evaporated. The chemical equation was used to predict the amount of NaCl that should be produced from the the combination of NaHCO3(s) and HCl(ag). We observed two different chemical changes when the solution became cold in the beaker of NaHCO3(s) and HCl(ag)

purpose of this experiment, which covered the concepts of heat and calorimeter, was to measure the specific heat of a metal and to compare the experimental result to the theoretical value of same metal. Theory: The relevant theoretical concept and equation used in this experiment were: ∆Q = change in the quantity of heat m = mass of the object ∆T = change in temperature C = heat capacity Heat capacity, C, is the quantity of heat needed to raise the system 's temperature by one degree. ∵∆Q = C∆T ∴C
