Background Research Sorting and Organizing Since the birth of civilization, organization has played an essential role in all aspects of life. The seven wonders of the ancient world could not have been built without extensive organization. The Egyptians made an impressive use of organization when they built the Great Pyramids. They had to organize their workers into different groups, each doing a different job. The architects also had to sort the bricks in order to build the pyramids. They sorted the bricks depending upon size and shape in order to reduce the amount of work they had to do shaping the bricks.1 This effectiveness of sorting can be seen today in the modern world. In recent times, sorting systems are automated requiring little human involvement. One company that uses sorting to make its company run faster and more efficient is DHL in Belgium. They have put into practice an automated sorting system called Verastream.2 Verastream can do the whole process of sorting, including weighing, measuring, and shipping without much human interference. Another company named Compac has an extensive sorting system that sorts produce by weight, color, blemish, shape, and density. Compac’s color sorting system uses an InVision 5000 Color and Demension System to sort its produce. This machine can distinguish between up to sixteen user-defined colors. In addition, it can choose the average color of the type of produce. After determining the 1 “Seven Wonders of the World - Pyramids of Egypt” 2 “Verastream Helps Automate Package Sorting for DHL” color of the produce passing through the machine, the produce can then be sent down the correct path.3 Compac’s color sorting system is similar to the soda sorting system. The soda sorting system uses a light sensor to sort the soda by color. When the consumer makes a choice of soda by clicking the corresponding button, the light sensor will look for the color of the corresponding soda. Once the light sensor acquires the correct soda, it will then send the information to another RCX. The other RCX will then find the correct type of soda, pick it up, and transport the selected soda to a soda can opener. The major advantage of the sorting machine compared to industrial sorting machines is that the robot sorter is much smaller. It is small enough to fit into a cabinet. Also this product allows an average person to have a remotely operated way of choosing a type of soda and bringing it to him or her. This is useful because a person may not want or be able to get up and get a soda for him or herself without missing part of his or her
The essential points of the green-frosting are the concentration and absorbance value in each diluted which the process of serial dilution. The standard curve of Blue#1 and yellow #5 provide the equation of the trend-line in order to calculate the concentration in the diluted solution of the green frosting. The mole of dye in 100mL green stock solution, mole of dye in 5 gram and 1 gram of frosting, the Beer –Lambert Law, and the compare to amount desired by the company can be determined. The Beer-Lambert Law is the relationship between color and the concentration and equation A=Ebc. The “A” is absorbance, the “C” is a concentration in molarity, the “E” is a molar absorptivity and “b” is the path-length. The goal of the lab is to use the absorbance and the Beer-Lambert law to determine the amounts of blue#1 and yellow #5 in the green frosting.
The red pigment and the green pigment will follow the alcohol higher on the coffee filter than the yellow pigment. There will only be chlorophyll left in the spinach leaf, the yellow leaf will contain chlorophyll and xanthophyll & the red leaf will contain chlorophyll, carotene, and xanthophyll. My hypothesis was supported.
Light sticks work in a similar way. When you “snap” a light stick, the chemical in the glass capsule mixes with a chemical in the plastic tube and creates light energy. Instead of the chemicals used by a firefly, other chemicals are used to create a glow. The light stick that you can buy at a store usually contains hydrogen peroxide, phenyl oxalate ester, and fluorescent dye (New York Times Company, 1 of 3). The light stick will glow the same color as the fluorescent dye placed in it. In luminescence, the chemical reaction “kicks an electron of an atom out of its ‘ground’ (lowest-energy) state into an ‘excited’ (higher-energy) state, then the electron give back the energy in the form of light so it can fall back to it’s ‘ground’ state (Fluorescent Mineral Society, 1 of 2).
This Experiment is a way of successfully viewing the emission spectra for metal carbonates. By heating the carbonates electrons go from there normal state called ground state to a higher energy state called excited state and the difference in electron energy gap of each metal carbonate makes up the difference of colours. This excited state is not a stable state but while in this state the atom gains additional energy but the variation of energy emitted is a characteristic of that in particular element. In this state the electrons emit photons which is the energy that corresponds to light wavelengths and therefore produces the different light emissions.
Enter the access code by using the drink selection buttons. The default access code is 4, 2, 3, 1, but the buttons aren't numbered. They will either say nothing or have pictures of Coke, Diet Coke, Sprite, and other Coca-Cola products on them.
other coloring. Likewise, the color range helps to demonstrate that there will be a shade
* It was almost impossible to tell when the Alka-Seltzer tablet had dissolved, each time the experiment was done. This was a huge problem for the experiment as this could have totally caused problems to the experiment. A special type of detector apparatus, which bleeped when the correct amount of Alka-Seltzer tablet dissolved, could improve this, each time the experiment was done.
Record any color changes of the strip and determine the glucose concentration according to the key on the bottle.
Limitations of Experimental Design- My experimental design helped answer the original question adequately. Since the syringes were small, wrapping them in colored film was relatively simple and took little time to do. Using colored film was also more effective than using colored bulbs, the original plan. Colored bulbs would have ...
simple as a hand to hold, or saying positive things to them to reassure them that it is for the better
Different people can also see color differently. We all agree the sky is blue, but a piece of reflective art may look slightly blue to one person while another sees it as slightly cyan. If you don't know the difference between the look of blue as opposed to cyan then communicating your preferences to a technician can be problematic. Subtle color variances are best seen under correct viewing conditions (not by a window, etc.) and can take some time to learn to even see them. Then when you can both see and discern these differences, then comes the task of communicating your choice for correction to a technician in the right terms (something I will cover soon).
Darker specimens will absorb more light and more bright patterns will absorb less light. The detector measures the amount of light that is transmitted through the sample. The various electronic components convert this measurement in% transmittance reading, which is a percentage of source light, which has made its way through the sample.
The electrons then emit a photon of light. The light for the corresponding wavelength is determined by specific energy level of the certain element, resulting in different colors to appear. Due to sodium’s photons, a yellow and orange light is projected. For the chloride anion tests, the silver salts found in the unknown compound were insoluble, because a mixture between sulfate and silver is insoluble according to the solubility rules; therefore, when mixed with nitric acid and with silver nitrate, a precipitate was formed. The anion would only be chloride if the other four tests proved to be negative. The sulfate anion test also proved positive, as a white precipitant was formed when the unknown substance was mixed with barium chloride and hydrogen chloride; the mixture between barium and sulfate is also insoluble according to the solubility rules. For the acetate, nitrate, and carbonate tests, the results came out negative because there was no definite chemical reaction with the
Attention getter: The Great Pyramid at Giza is the only one of the Seven Wonders of the Ancient World, still standing.
The labels have fallen off of two bottles thought to contain solid sodium chloride or solid sodium carbonate. Describe a simple experiment which would allow you to determine which bottle contains which solid.
