Fahrenheit 9/11

Introduction: There is a direct relationship between temperature and pressure in gases. The relationship can be proven by measuring pressure, which is measured with a pressure sensor, and temperature, which is measured with a temperature probe. Two areas remain constant throughout this experiment, which are volume of the gas and the number of molecules the gas itself contains. In this experiment, using the constructed apparatus, an Erlenmeyer flask with an air sample will be placed in four…

Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain…

Intriguingly, as the conducted experiments disclose, isobutanol possesses an experimental boiling point approximately 23℃ higher than that of tert-butanol. Additionally, the boiling point of isobutanol appears to be 9℃ higher than that of sec-butanol. The latter had been a surprising, perhaps anomalous result indeed, since sec-butanol maintains a longer straight-chain skeleton of carbon atoms (four, to be precise) than either of the former two alcohols, whom possess…

temperature in °C, the mass of the water in grams, and the specific heat of water as 4.184 J/(g · °C). This will then put your answer in Joules. Be sure to use the correct number of significant figures in determining the heat absorbed by the water. 9. Now you can use equation 12.3. Since we are ignoring the calorimeter in the experiment, q(calorimeter) = 0. You calculated q(water) in the previous step, so you can determine q(metal). It will come out negative because the metal lost energy.…

In late 2015, scientists found that the best borrowers are not, in fact, the characters of the 1997 movie, but microscopic animals called water bears. Water bears, more specifically named tardigrades, are found to have scavenged about 17.5% of their genes from other creatures. This ability to obtain used genes from other creatures’ discarded DNA is found to let tardigrades undergo extreme stress. And not just homework stress. Tardigrades live in water, and have to be submerged to survive.…

Common house crickets, Acheta domesticus, were provided by the instructor in three colonies in three separate containers based on their size, small, medium, and large. Ten crickets was retrieved from the small colonies and placed into a beaker. The crickets were individually removed from the beaker and placed into separate small capped vials. The weight of the vial containing the cricket was weighted using a balance scale. The cricket was then removed from the capped vial and placed into a…

Transcript Transcript of American Alligator (Alligator mississippiens) SCIN 130 Power Point presentation by Serena L. Sobolewski Introduction: The organism that I have chosen for this assignment is an animal, of the crocodilian family, called the American Alligator. The scientific name is Alligator mississipiens In Spanish it is is called El Legarto, meaning the lizard. The habitat preferred by the American Alligator is fresh water swamps, marshes, rivers, lakes, and occasionally smaller…

RESEARCH QUESTION: This experiment will analyse the changes in performance of a cane toad in abiotic factors, such as temperature. HYPOTHESIS: Cane Toads exposed to a warmer temperature will more times per minute compared to cane toads exposed to a cooler temperature. METHODS: 16 cane toads were kept at a constant temperature in an insulated container (two treatments: 8 in 25 degree Celsius and 8 in 15 degree Celsius temperate environments). Toads were then taken out, one by one, and placed…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…
