Atmospheric thermodynamics

Part 1: Test of Melting Point Generally, ionic solids have very high melting point temperatures. Covalent molecules have a lower melting point. Polar covalent molecules have a higher melting point than non-polar covalent molecules. 1. Mold an aluminum foil boat that will serve as a tray for the table salt, sugar, wax. 2. At different corners of the boat place a very small amount of each substance. a. Table Salt b. Sugar c. Wax 3. Set the hot plate on high. 4. Observe and record the order…

1. Fill a mason jar half-full with tepid water. Put it on the hotplate and raise the temperature to 98 degrees. Make sure you can keep it at this temperature for several hours. 2. Wash your hands. Cover the surfaces adjacent to your kitchen stove with paper towels. Place the test tube racks close to the stove on the paper towels. 3. Fill the pot with water and bring to a boil. Uncap your test tubes. Using your kitchen tongs, carefully drop your graduated cylinder, test tubes and their caps in…

Brandon Thai 5/17/17 Freezing Point Depression Abstract The freezing temperature of pure Cyclohexane and a solution of Biphenyl and Cyclohexane was determined. This was done by examining the temperature curves for each solution. The freezing temperature for pure cyclohexane was determined to be 7.3 degrees celsius and the mixture of Biphenyl and Cyclohexane was 2.07 degrees celsius. Introduction The purpose of this experiment is to determine the freezing point for pure cyclohexane and a…

1. For part 1, is the theoretical final temperature the same as the measured temperature? Explain any difference. No, in part 1, the theoretical final temperature is not the same as the measured temperature. This is caused by the base assumption of the ‘Principle of Heat Exchange’, which is that the principle only holds true if heat is not lost to its surroundings. Although, the loss of heat to its environment (ex. Desk, air, cup, etc.) was attempted to be minimized by quick transfer of the…

The Deathly Dog Days of Summer With summer right around the corner, many people will be out and about doing all the things that could not be done during the dreary months of winter. Although summer is filled with activities, the heat of the day could put you at risk. Overheating can lead to heat exhaustion or even a heat stroke. Knowing the signs could save your life or others. Heat exhaustion and heat stroke may be caused by a number of reasons, while the repercussions can be detrimental to…

It is believed that at higher potential foils can be overheated and deformed, which can quench the reaction propagation. The quenched reaction front with deformation will be explained in more detail in the next section. The reaction front speed of 1Ti/2Al reactive foil is nearly constant for different potentials. The high conductivity of this foil type and moderate diffusion distance of atomic mixing exhibit nearly constant reaction velocity. With increasing activation potentials, the reaction…

Gravimetric Determinations of BaCl2 from a mixed sample Dharmin Chauhan CHEM 1411 June, 25th, 2016 Introduction Gravimetric Determinations of BaCl2 from a mixed sample is the name of the experiment. This experiment also known as gravimetric analysis. Gravimetric analysis is the calculation of analyte concentration precipitation, isolation, and weighing (Filho, 2014). The two key concepts to note in this experiments are Gravimetric analysis and…

The capillary column is held in an oven that can be modified to build the temperature step by step (or in GC terms, sloped). This helps our partition. As the temperature expands, those compounds that have low boiling points elute from the column quicker than those that have higher boiling points. Subsequently, there are really two unmistakable isolating forces, temperature and stationary phase specified beforehand. As the mixes are isolated, they elute from the segment and enter an indicator.…

As part of your upcoming Employee Performance Review (EPR), please complete the following questions: How is your enthusiasm for your job, and why? I enjoy my job and look forward to coming in every day. I enjoy that there is something new each day and that we get a chance to help our Team members grow. The main reason why I enjoy working here is the Culture. How dedicated or focused toward your job do you feel, and why? I feel that I probably dedicate too much of my time focusing on my…
