Indeed‚ the US and Mongolia are located far from each other ; they have many similarities. For example‚ both US and Mongolia have huge land and many varies of climate and landscape. Due to large size‚ varies across the large country from tropical beaches to Alaska while Mongolia have many different places from Gobi

EA1031.31.05 05 Oil Characterization.pdf 2 Oil Characterization Workshop The petroleum characterization method in HYSYS converts laboratory analyses of condensates‚ crude oils‚ petroleum cuts‚ and coal-tar liquids into a series of discrete hypothetical components. These petroleum hypo components provide the basis for the property package to predict the remaining thermodynamic and transport properties necessary

about how foods react to and inter-act with each other in a culinary or scientific manner‚ all I know is I really like to dip things in chocolate. My problem I had was that my chocolates kept burning‚ even though I was using the same method (double boiling) to melt each type of chocolate. I couldn’t understand why each of them reacted differently to the same method of heating (physical stimuli). I was thinking how cooking is like a science experiment in some ways. For example‚ you come up with an

body is of two thirds of water. It is clear‚ colourless liquid that appears blue when viewed through a thickness of 20 ft. The colour reflects not only from physical causes but also from suspended impurities. The freezing point of water is 0degree centigrade and its boiling point is 100 degree centigrade. Water is the most essential component of life and is vital for sustenance. The importance of water in our diet is apparent as it helps the body to perform specific metabolic tasks and regulates

What are some steps you could take to improve the reliability and repeatability of your results?) Point: Although most variables were controlled for‚ the repeatability of this lab could be improved by including the following steps. Make sure the lab is quiet and distraction free at all times. This is important to the experiment because when a scientist

Chem 205 I. Title and Equation: Unimolecular Elimination + 2 Isomers II. Experimental Procedure : In a flask‚ 0.081 mol of 2-methycyclohexanol and 3 mL of 85% H3PO4 were mixed. The mixture was boiled under a fractional distillation column‚ and 7 mL of the distillate was collected. The organic and aqueous layers were separated and the organic layer was dried with anhydrous sodium sulfate. The product was analyzed using GC. III. Conclusion: In this experiment‚ 2-methylcyclohexanol

representation of a dry refrigeration cycle Refrigerant fluid choice: We now turn our attention to the fluids. Usually‚ one tends to pick pL as low as possible‚ but not below atmospheric pressure. Thus‚ the refrigerant chosen needs to have a normal boiling point compatible with the lowest temperature of the cycle (usually 10oC lower than the system one wants to cool). The higher pressure needs to be compatible with the cooling
