Before reading, I assumed "The Cold Equations" was science-fiction oriented. Perhaps it was a darker telling of space travel or what the world would be like in the future. To describe the dark, dangerous depths of space. To my own surprise, I was not wrong! I feel the author was trying to portray real world dilemmas with futuristic settings. In my opinion, it told a rather grim tale from the start. I thought the setting and themes, though dark, were interesting and told well enough to motivate me to keep reading. Space travel has always been an interesting concept to me, and The Cold Equations opened my eyes to the "what ifs" of a modern-day world of galactic colonies. It kept a level-headed story in an often day-dreamed environment; something

Essay on Design of Machine Elements

1.0 Introduction The transfer of heat normally involves the change in temperature of an object with high temperature to another object with lower temperature. According to the First Law of Thermodynamics, heat transfer changes the internal energy of both systems involved. As such, the three modes of heat transfer are; Conduction, Convection and Radiation. According to C.R. Nave (Hyper Physics, 2010), conduction is heat transfer by means of molecular agitation within a material without any motion…

Essay on Lab 4 formal report

capacity of the calorimeter is determined, that is, the amount of energy needed to raise its temperature by 1°C (or K). In order to do this, a known mass of cold water will be added to a known mass of hot water in the calorimeter. As heat is lost by the calorimeter and by the hot water while begin absorbed by the cold water, the following equation can be used to determine the calorimeter’s heat capacity: . The calorimeter used is not a sealed system. Consequently, the reactions occur at constant pressure…

Nucleophilic Acyl Substitution Lab Report

The goal of this preparative experiment was to create acetaminophen through a Nucleophilic Acyl Substitution reaction. In this reaction, p-aminophenol reacted with acetic anhydride to create acetaminophen. The new skills learned include vacuum filtration, and decolorizing of the crude product. In the experiment, vacuum filtration was used to extract any solution from the crude product so that all of the solid crude product could be well collected and for purification purposes as well. Decolorization…

Photosynthesis Lab Report

If there is no presence of oxygen then the cycle goes directly to ethanol lactic acid and glycolysis, this whole process is called fermentation. Our formula for when there is no oxygen present is Also 2atp and 2H2O are the products of this equation. This process is called anaerobic. If there is a presence of oxygen then the formula changes to This includes 36 ATP. The point of this experiment is to see the rate of a reaction of carbon dioxide happening in the yeast at different temperatures…

Synthesis and Chemistry of K2S2O8 Essay

prepared and to this solution, 1.5mL of pyridine was added slowly while stirring, followed by 3mL of silver nitrate solution (5% w/v, 8.83E-4 mol). The solution was cooled to below 10 °C and the orange solid formed was filtered, washed with 5mL of ice cold water, then twice with 5mL of alcohol. The above amount of reagents yielded 0.158 g (43.04%) of [Ag(py)4]S2O8. RESULTS Table 1 REACTIONS OF PEROXODISULFATE AND HYDROGEN PEROXIDE Reactions Peroxodisulfate Hydrogen Peroxide 1) Acidified…
