respective rules. Though Communist leader Pol Pot and German nationalist Adolf Hitler can be compared in several ways‚ there are also myriad differences between their ascendancies. The social dispositions and executions of Adolf Hitler and Pol Pot‚ although similar in several ways‚ also differed for numerous reasons during their supremacies. The social perspectives and exploits of Hitler and Pol Pot have multiple similarities. For example‚ both Pol Pot and Hitler advocated and‚ to an extent‚ succeeded

Freeze! The Effect of Super Cooling Water on Nucleation in Aqueous Solutions Hunter B. Tuck Author Note Hunter B. Tuck‚ Southside Virginia Community College‚ Keysville‚ VA. Contact: huntertuck1212@gmail.com Abstract This particular study demonstrated the overall effects of super cooling different types of aqueous solutions. In similar studies conducted upon super cooling water‚ researchers have only used distilled water in their experiments. In this study‚ however‚ rain‚ tap‚ and purified bottled

Casting Defects: Some defects are common to any and all process. These defects are illustrated in figure briefly described in the following: [pic] A) Misruns: A Misrun is a casting that has solidified before completely filling the mold cavity. Typical causes include 1) Fluidity of the molten metal is insufficient‚ 2) Pouring Temperature is too low‚ 3) Pouring is done too slowly and/or 4) Cross section of the mold cavity is too thin. b) Cold Shut: A cold shut occurs when two portion

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis

6. Results and Discussion 6.1. Mix Design of Cold Recycled Bituminous Mixture Compaction characteristics of untreated bitumen mixes according to Modified Proctor Test is shown in Figure 6. When the RAP content increased‚ it resulted in reduction of MDD and the corresponding increase in OMC. The decreased MDD is obtained due to the weak bond between RAP and the virgin material and also due to less fine material that plugs the voids to produce denser mix. The corresponding increase in OMC is

Purpose: The purpose of this lab was to determine the freezing point of pure water‚ the experimental van’t Hoff factor for a substance and the molar mass of an unknown solution. Reagents: 25mL deionized Water ¼ to ½ inches of rock salt 25mL Sodium Nitrate (NaNO3 ) 25mL unknown solution – handle unknown solution carefully Procedure: For part 1‚ the freezing point of deionized water was determined. An ice bath was prepared by filling a 600mL beaker ¾ full of ice and covered with ¼ to

world’s ice is slowly melting‚ so that also means our glaciers are melting (shrinking). This is a problem worldwide. The oil‚ coal‚ natural gases‚ and fossil fuels we burn affect our atmosphere and increase the temperatures that melt our glaciers. If the glaciers continue to melt rapidly ocean levels will rise‚ there will be flooding‚ there also could be droughts. This is a very serious issue today but I’m just going to tell you about two places for now. How does the melting of glaciers affect people

Potoooooooo or Pot-8-Os (foaled in 1773) was a famous 18th-century Thoroughbred racehorse‚ known for his defeat of some of the greatest racehorses of the time and his later life as an influential sire. Pot-8-Os was a chestnut colt bred by Willoughby Bertie‚ 4th Earl of Abingdon‚ in 1773. He was sired by Eclipse‚ his dam Sportsmistress traced to Thwaites’ Dun Mare from the number 38 family and she was sired by Warren’s Sportsman. He was the first foal of Sportsmistress‚ who also produced the Epsom
