Majority of glass used in our daily glass from jars, bottles, drinking glass and even windows are called soda-lime glass since it uses soda ashes in its production. Glass in general is mainly made out of sand. In fact, sand alone can be fused to produce glass but it requires a high temperature which is estimated about 1700°C for the sand to completely melt. However, to mass produce glass, other chemical and mineral are added to lower the melting temperature to ease the production.
Sodium Carbonate (Na2CO3) also known as soda ash is mixed with sand to produce a product of 75% silica (SiO2) and 25% sodium oxide (Na2O). This mixture will melt and fuse at a much lower temperature of 800°C. Unfortunately, the glass produced with this composition is water-soluble which is also known as water glass. This is not suitable for glass bottle since it need to contain water so, to stabilise the glass, other chemical substance is mixed into the composition such as calcium oxide (CaO) and magnesium oxide (MgO). The chemical mixtures are obtained by the addition of lime stone which produce a pure and inert glass.
The glass produced is originally colourless and transparent. Addition of different chemicals into the production of the glass results in different colour like green blue or brown. Most of glass bottle produced have similar composition of chemicals as their ingredients. The composition of chemicals are 70% - 74% SiO2 (silica) 12% - 16% Na2O (sodium oxide) 5% - 11% CaO (calcium oxide)
On average the Alka Seltzer tablet dissolved faster in hot water in comparison to ice cold water and room temperature water. The beaker with ice cold water caused the Alka Seltzer tablet to dissolve the slowest. The three beakers containing different temperatures of water, all produced carbon dioxide bubbles; however, the beaker containing hot water produced the bubbles more rapidly.
The colorful look of dichroic glass is only achievable through thin film physics, and process that gives bubbles their rainbows and dragonflies their colorful wings (Smedley). In occurs when one light wave hits a thin film. Part of the wave is reflected as some continues to travel through the film, diffracting slightly as it enters the new medium. The continuing wave then encounters another new medium where it is reflected back. This reflected wave then interferes with the first reflected wave. This causes the colorful spectrum that can be seen in a dichroic glass
Though many people will think there is a lot of bad in soda, technically it’s just carbonated water, which is basically “gas that’s called carbon dioxide that has been dissolved under high pressure” (sciencebuddies.org). When one opens a can of soda pop the carbon dioxide in it is released out causing the bubbles in the drink, and the best part for this project is that one can choose their own way to do it, yes they may have to follow what the recipe calls for but they can choose their favorite flavors and their own color for it like if they wanted to they could make a bacon flavored pop but it might not taste the best but the point would be that it would be their own idea.
As a young child, my grandmother’s china cabinet was enchanting. When the sun streamed through the cabinet at the perfect angle, pink patterns created by glass dishes were splayed on the green shag carpet. Of course, I was not interested in the glassware that produced the light display, I was just intrigued by the display itself. As I grew, my grandmother explained these two pale pink glassware sets were known as Depression Glass. Like many other women, my great grandmother collected the sets piece by piece, and they became her pride and joy. Although they may not be made of high quality glass, these cups, plates, and bowls are priceless family heirlooms that remind us that beauty can be found in the bleakest of times, even during the
“Life with your father was never boring.” – Rose Mary Walls. Rose Mary Walls, Jeannette Walls’s mother and Rex Walls’s spouse, reminisces life with Rex, which included migrating frequently, refusing to conform, and advocating self-sufficiency. Despite Rose Mary finding Rex disdainful at times, she still believes that being with Rex was an adventure. In Jeannette Walls’s The Glass Castle, Walls reveals that there are turbulence and order in life, the influence of family, and how she develops as she grows up through Walls’s recollection of her life, from living in a nomadic household, where her parents neglect their children, to living in a squalid hovel with no plumbing, and finally living in New York City, where she is employed as a journalist.
Cinderilla or The Little Glass Slipper was written by Charles Perrault. The main characters of the story are Cinderilla, the two sisters, the step mother, and the King’s son. Throughout the story the step sisters and step mother despite and envy Cinderilla. They treat Cinderilla badly and call her hateful names like “Cinderbreech.” As a result, the story, “Cinderilla,” teaches readers that jealousy and envy can lead to the downfall of a person because it causes insecurities, and unhappiness.
Once cooled, the mixture was then transferred to a separatory funnel using the funnel while avoiding adding the boiling chip. 10 ml of water was then added to the mixture. The mixture was gently shaken and the phases were allowed to separate. The funnel was then unstopped and the lower aqueous phase was drained into a beaker. 5 ml of 5% aqueous NaHCO3 was added and then shaken gently. A great deal of caution was taken into consideration because of the production of carbon dioxide gas which caused pressure to develop inside the funnel. The pressure needed to be released so the funnel was vented frequently. The phases were allowed to separate and the lower aqueous phases was drained into the beaker. After draining, 5 ml of saturated NaCl was added to the funnel and then shaken gently. Once again, the phases were allowed to separate and the lower aqueous phase was drained into a beaker. An ester product was produced and was transferred into a 25 ml Erlenmeyer flask. This organic product was then dried over anhydrous Na2SO4 to trap small amounts of water in its crystal lattices thus removing it from the product. Finally the ester was decanted, so that the drying agent was excluded from the final product.
There are many methods in which providers are reimbursed for services. Some of these methods are:
Safelite Auto glass introduction of the proposed PPP plan to increase the productivity of the installers is going to bring more problems for the organization. One of the major reasons for this is the decrease of the technicians guarantee rate by 30% after 12 week period. This plan will increase the already existing turnover rate even higher. The problem with the PPP rate is that not all technicians will get the opportunity to increase their productivity. The first reason for this is the varying demand for the windshield around the year, during winter the demand is less which in turn provides less number of jobs per day for the technicians which can be less than the targeted PPP rate. So if the
There are a variety of tools and equipment used in the glassblowing process. Three of which consist of three very large furnaces. The first furnace melts the glass and keeps the glass hot. The melted glass inside the first furnace is referred to as batch. The furnace keeps the batch at over two-thousand one hundred degrees Fahrenheit. The glassblower then takes a long pipe, about four feet long, and places it inside the furnace. In addition, the glass pipe is heated to a really hot temperature so that the glass will adhere to the metal rod. If the rod is not heated, the glass will not stick to the rod. The pipe used to collect the molten glass is called
There are families that are living with more than just their family. When grandparents, aunts, uncles, brothers, and sisters live under the same roof, this is called multigenerational home. The benefit of living in a multigenerational home is that the family grows closer together, and has special bonds. The challenge of living in a multigenerational home is when you have to spend every single day with each other. In a multigenerational home it is a family household consisting of three or more generations, the challenge is respecting the elderly ones in the home, and the benefit is that the grandparents, if in good health and shape, can help with the children.
The Ojibwa are an Aboriginal individuals in Canada and the United States who are a piece of a bigger social gathering known as the Anishinaabeg. They are firmly identified with the Odawa and Algonquin people groups, and offer numerous customs with neighboring Cree individuals, particularly in the north and west of Ontario, and east of Manitoba. In their conventional countries in the Eastern Woodlands, Ojibwa individuals got to be indispensable parts of the early hide exchange economy. Ojibwa society, dialect and activism have continued regardless of assimilative endeavors by elected and commonplace governments, and much of the time are illustrative of the persisting First Nations vicinity in Canada (Bishop, 2008). The historical background
Ethanol fuel is typically just made from plant biomass by pretreatment, fermentation, and distillation, which is very much the same way that beer and liquors are produced.
My hypothesis is that if I add different amounts of sugar to the same amount of boiling water and allow it to be cooled, than the one with the additional cup of sugar will be the one that grows more crystals. I determined that my hypothesis was correct. The glass I chose to add the pure cane sugar did grow much more crystals at a
