Fluorocarbon Essays

“Upon checking a frozen, compressed sample of tetrafluoroethylene, he and his associates discovered that the sample had polymerized spontaneously into a white, waxy solid to form polytetrafluoroethylene.” (History of Teflon, year) Polytetrafluoroethylene, PTFE, more commonly known as Teflon was not invented, meaning it was made for a reason, but discovered by accident by Dr. Roy Plunkett in 1938. Teflon is one of the many serendipitous discoveries that have become very helpful and used frequently

chlorine atoms that are replaced by hydrogen atoms causes a higher presence and both are covalent bondings with strong intermolecular forces. The double bondings (Or triple bondings) in hydrocarbon tends to be stronger, but the chemical is flammable. Fluorocarbons are not flammable and are also polar covalent bondings, making them stable to ultraviolet radiation and prevents them from catalysing ozone depletion. Hydrochlorofluorocarbons (HCFCs), one of the alternatives that contains C-Cl bondings have most

Global warming To blame people or not to blame people for global warming, that’s the question. Global warming is an raise in temperature over the whole world. Report has said, eleven out of the last twelve years have ranked amongst the hottest on record. CNN has said that temperature changes have been see over the last fifty years, as result to human actions. Scientists have forecasted that the temperature will raise 1.8 to four degrees Celsius. Yes people are guilty of global warming because of

hiding your hook completely in a bait, throw in some chum, and let your bait free sink down with it. You can pull line off by hand to make the bait sink naturally in the water. This works great many times. To increase effectiveness try using a fluorocarbon leader to decrease the visibility of the line. Be careful when handling bait. When using live fish for bait, try to cradle them in your hand rather than grabbing them hard. If they are wiggling around too much for you to easily put them on the

Ganzel, B. (2007). Frozen Foods during the 1950s and 60s. Retrieved November 28, 2016, from http://www.livinghistoryfarm.org/farminginthe50s/life_15.html This article breaks down the technology of food throughout centuries and the mechanized success. Food technology of food changed the way the world eats and the way of agriculture. “Frozen foods exploded – in a good sense.” Here, I found the history of how humans preserved perishable foods through ice storing and the evolution of cold storing food

Global Perspectives Line of Enquiry – Technological advances for a comfortable life Country – Japan  Generally, weather and climate are said to be the same. This is not true. The difference between them is a measure of time. Weather is what conditions of the atmosphere are in a short period of time. While, climate is how the atmosphere ‘behaves’ in a relatively longer period of time. Climate includes the patterns of temperature, precipitation, humidity, wind and seasons.  What is climate change

Deforestation is the process of cutting down and destroying trees in a habitat/ecosystem for human advantage, usually profit. Of all the areas on Earth being deforested, the Amazon Rainforest is the largest target. Over 750,000 square kilometers of The Amazon Rainforest have been destroyed across Brazil, Peru, Bolivia, Colombia, Venezuela, Guyana, and French Guiana. 79% of deforestation of the Amazon takes place in Brazil. Rainforests are cut down for a variety of reasons, mostly for agriculture

Nylon 66 is a type of polyamide or nylon. It is most commonly found in fishing nets, ropes, cords and fishing line making it the camping and leisure material of the century. It is made up of two monomers which each containing 6 carbon atoms, hexamethylenediamne and adipic acid (figure 1.), which give nylon 66 its name. This specific type of nylon was invented by Wallace Carothers at DuPont’s research facility on the 28th of February, 1935. Properties of this polymer that make it the best

Aerogel Insulation Energy loss is a common issue in buildings. Heat energy escapes a house through windows, doors, walls or ceilings. Meanwhile cold air infiltrates a house reducing the heat energy within it. ("Heat Gain and Loss Explained."). Up to 35% of heat loss occurs through walls and almost 25% through roofs, the other heat is lost through windows doors and the floor (Jimbo.). Heat energy loss has numerous disadvantages, for instance the high costs it results with. In the case that the

The transformation of technology has spectacularly changed our humankind. Majority of the people all over the world consumed technology and gained profit out of it. The vast prospects and events it provides to human race displays a loyalty to almost every path of community. Technology has made simple by providing allowance to the required equipment essential for humanity in the position of medicines, industries, transportation, communication and education. Nonetheless, consumption of technology

of toxins, chemicals such as hydrochloric acid; muriatic acid; hydroxyethyl cellulose; glutaraldehyde; petroleum distillate; ammonium bisulfate; 2-hydroxy-1,2,3-propanetricarboxylic acid; N Dimethylformamide; ethylene glycol; 2-butoxyethanol; fluorocarbons; naphthalene; butanol; or formaldehyde are often released to the surface. (law) The chemical 2-butoxyethanol ("EGBE") is a major of concern to human health. Millions of gallons of EGBE are released in waste products over the years and are absorbed

The Incredible Hulk, though a fictional character, is a hero to many people of all ages. The Hulk and his alter ego, Bruce Banner, are polar opposites. Though The Hulk and Bruce Banner are this way, occasionally glimmers of Bruce’s personality shine through in the way that The Hulk behaves. The Hulk relates to many mythological characters. He most greatly relates to Hercules. The Hulk also relates to Perseus in several ways, but there are also many differences between the two as well. The Hulk

CLIMATE CHANGE DUE TO GLOBAL WARMING Climate changes due to global warming has been a global concern. Climate change it has effected our economy, health and communities in a very bad way. What do you think we will be able to do to prevent this? Global warming? Is it real? Global warming is defined as a gradual increase in the average temperature of the earth’s atmosphere. The evidence of global warming is all around us. For example, sea level rise : rise in the water level in the sea. Every year
