Bar to Atm - Converting Bars to Atmospheres Pressure

These example problems demonstrate how to convert the pressure unit bar (bar) to atmospheres (atm). Atmosphere originally was a unit related to the air pressure at sea level. It was later defined as 1.01325 x 105 pascals. A bar is a pressure unit defined as 100 kilopascals. This makes one atmosphere nearly equal to one bar, specifically: 1 atm 1.01325 bar. Helpful Tip Convert bar to atm When converting bar to atm, the answer in atmospheres should be slightly lower than the original value in bars. Bar to Atm Pressure Conversion Problem #1 The air pressure outside a cruising jetliner is approximately 0.23 bar. What is this pressure in atmospheres? Solution:1 atm 1.01325 barSet up the conversion to the desired unit will be canceled out. In this case, we want atm to be the remaining unit.pressure in atm (pressure in bar) x (1 atm/1.01325 bar)pressure in atm (0.23/1.01325) atmpressure in atm 0.227 atmAnswer:The air pressure at cruising altitude is 0.227 atm. Check your answer. The answer in atmospheres should be slightly less than the answer in bars.bar atm0.23 bar 0.227 atm Bar to Atm Pressure Conversion Problem #2 Convert 55.6 bars into the atmosphere. Use the conversion factor: 1 atm 1.01325 bar Again, set up the problem so the bar units cancel out, leaving atm: pressure in atm (pressure in bar) x (1 atm/1.01325 bar)pressure in atm (55.6/1.01325) atmpressure in atm 54.87 atm bar atm (numerically)55.6 bar 54.87 atm Bar to Atm Pressure Conversion Problem #3 You can also use the bar to atm conversion factor: 1 bar 0.986923267 atm Convert 3.77 bar into atmospheres. pressure in atm (pressure in bar) x (0.9869 atm/bar)pressure in atm 3.77 bar x 0.9869 atm/barpressure in atm 3.72 atm Notes About Units The atmosphere is considered to be an established constant. This does not mean that the actual pressure at any point at sea level actually will be identical to 1 atm. Similarly, STP or Standard Temperature and Pressure is a standard or defined value, not necessarily equal to actual values. STP is 1 atm at 273 K. When looking at pressure units and their abbreviations, be careful not to confuse bar with barye. Barye is the centimeter-gram-second of CGS unit of pressure, equal to 0.1 Pa or 1x10-6 bar. The abbreviation for the barye unit is Ba. Another potentially confusing unit is  Bar(g) or barg. This is a unit of gauge pressure or pressure in bars above atmospheric pressure. The units bar and millibar were introduced in 1909 by the  British meteorologist William Napier Shaw. Although the bar is still an accepted unit by some European Union countries, it has largely been deprecated in favor of other pressure units. Engineers largely use a bar as a unit when recording data in pascals would produce large numbers. The boost of turbo-powered  engines is often expressed in bars. Oceanographers may measure the  pressure of seawater in decibars because the  pressure in the ocean increases roughly 1 dbar per meter.

Gender Roles And The Potential Impact On Children s...

Children’s Programming; Stereotypical gender roles and the potential impact on children’s gender identity socialization. ‘Media corporations, with a commanding role over commodity markets have become the primary educational and cultural force in shaping, if not hijacking, how youth define their interests, values and relations to others’. (Giroux 2011) My argument throughout this essay will be that children’s programs have a significant impact and influencing effect on shaping and forming a child’s identity. It is without doubt that children’s programming will have a deep profound impact on a child. From the ages of 2-12 a child is most impressionable, easily convinced and persuaded by outer and exterior influences. A child will be most naive, gullible and extremely trusting to outer powers. Children are easily manipulated and therefore anything they are exposed to will have an effect on what they proceed to think, feel and do. . When they are exposed to certain words, people, experiences, or indeed to certain television programmes, they begin to imitate, impersonate an d mimic what they see. Furthermore, The American Medical Association reports that the combined hours spent in front of a television or video screen is the single biggest chunk of time in the waking life of a child.’ So with this added factor, undoubtedly the amount of time children are spending watching television is going to have an impact The four main children’s programs I have chosen toShow MoreRelatedThe Social Aspect Of School1381 Words   |  6 Pagesfunctions of schooling greatly influenced my identity; these functions are socialization and future preparation.

Genetically Modified Organisms Essay Example For Students

Genetically Modified Organisms Essay Genetically modified organisms (GMOs) or transgenes are organisms that have artificially introduced new genes with new qualities and traits. It is important to admit in the introduction, that the pace of development of world production using genetically modified organisms (GMOs) is impressive. Products with transgenes differ from ordinary ones neither in taste, nor in color, nor smell. Often they are used for the production of cooked sausages, canned meat, beer, chips, various sauces, instant soups, chocolate, syrups, and even baby food. That is, they are present in those products that include genetically engineered soy. In the course of scientific research and thesis, it was found that immunity was reduced in rats consuming modified potatoes. After the consumption of genetically modified tomatoes, animals had abnormalities in the tissues of the stomach, decreased brain volume, negative effects on the functions of the liver, spleen, intestines, glands, etc. History of GMO research The first GMO food was E. Coli cultivated in 1973. In the 90s of the twentieth century, intensive studies were conducted on the creation of transgenic plants, with the aim of improving their useful qualities and yields. Among them: corn, soybeans, canola, and cotton. The advantages of genetically engineered plant varieties are obvious—they are resistant to diseases, droughts, herbicides, pests, viruses, cold-resistant, give a good harvest, which can be maintained for a long time and without loss. Some types of modified plants may be invulnerable to chemicals that at the same time may be deadly to other plants. As a result, the field is freed from all weeds, and herbicide-resistant crops survive. Of course, the economic benefits of growing genetically modified plants make it indisputable. Example of products signaling possible GMO food content: lecithin, cottonseed oil, palm oil, corn syrup, butter, starch, soy. Possible effect on the human body The use of GM foods, according to scientists causes a surge in cancer diseases, allergic reactions, infertility, and a source of other dangerous ailments for a human. For example, the introduction of the Brazil nut gene into soybean DNA (to increase protein content) led to the fact that these agricultural crops have become dangerous for people who are allergic to nuts. Most of the known genetically modified plants resistant to herbicides are able to accumulate them. The confirmation experiments with rats that consumed genetically modified soybean resistant to the herbicide. These animals subsequently reproduced into inferior offspring, where more than 50% of the individuals were not viable. The new proteins present in the genetically modified plant also affects human health. In the process of creating GMO foods, it is impossible to predict exactly what part of the genome a new gene will â€Å"integrate.† The stability of the plants genome is disturbed, which often leads to the appearance of toxic properties of the product. Scientists in the argumentative essay insist on eliminating GMO foods from infant formula completely. The childrens body reacts sharply to alien proteins, to which it is not adapted. This is because of high allergic sensitivity. Since 2004, in the countries of the European Union, the use of GMO foods for baby (up to 4 years) is strictly prohibited. Most countries in the world have started a movement for the creation of genetically modified gm foods free zones. In January 2000, a biosafety protocol, known as the Cartagena Protocol, was adopted. The document came into force in 2003, after it was ratified by 50 states of the world. The protocol declares the rules for the processing and use of all living genetically modified organisms that may adversely affect human health. .uec2511d2f99d2ee0728230b35f06c269 , .uec2511d2f99d2ee0728230b35f06c269 .postImageUrl , .uec2511d2f99d2ee0728230b35f06c269 .centered-text-area { min-height: 80px; position: relative; } .uec2511d2f99d2ee0728230b35f06c269 , .uec2511d2f99d2ee0728230b35f06c269:hover , .uec2511d2f99d2ee0728230b35f06c269:visited , .uec2511d2f99d2ee0728230b35f06c269:active { border:0!important; } .uec2511d2f99d2ee0728230b35f06c269 .clearfix:after { content: ""; display: table; clear: both; } .uec2511d2f99d2ee0728230b35f06c269 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uec2511d2f99d2ee0728230b35f06c269:active , .uec2511d2f99d2ee0728230b35f06c269:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uec2511d2f99d2ee0728230b35f06c269 .centered-text-area { width: 100%; position: relative ; } .uec2511d2f99d2ee0728230b35f06c269 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uec2511d2f99d2ee0728230b35f06c269 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uec2511d2f99d2ee0728230b35f06c269 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uec2511d2f99d2ee0728230b35f06c269:hover .ctaButton { background-color: #34495E!important; } .uec2511d2f99d2ee0728230b35f06c269 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uec2511d2f99d2ee0728230b35f06c269 .uec2511d2f99d2ee0728230b35f06c269-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uec2511d2f99d2ee0728230b35f06c269:after { content: ""; display: block; clear: both; } READ: Diabetes Mellitus EssayDespite this, GMO products dominate the global food market. Currently, researchers are looking for ways to create a new generation of highly efficient, and at the same time safe, GMOs. On a note: When purchasing food (especially for children), it is necessary to remember: the presence of components such as corn oil, corn syrup, corn starch, soy protein, soybean oil, lecithin, soy sauce, cotton oil in their composition can be indicative of they are GMOs. The advantages of GM foods are that you can very good control everything that happens on the field, greatly reduce losses due to pests, frost and much more. But the disadvantages are that this is still a technology that has not been rolled in, despite the fact that genetically modified organisms are the most studied organisms for agricultural purposes, as they have been studied comprehensively. But so far there are no statistics on their use in agriculture, and many are afraid that gene modifications can escape from these plants, despite assurances from biotechnologists that this cannot be, and so on. In my opinion, genetically modified gm foods are a fairly safe thing. Those tests that are carried out with them provide a very high probability of no problems. But one should not forget that in nature, in the evolution of the same agricultural crops, genetic modifications also occur, only not directed, but completely nonspecific. And if in the case of GMOs there are cons and we can say that we have read, sequenced the genome of GM plants and know what is in it, and then we cannot say the same about other cultivated plants and there are some pros. We can receive the same harm that can occur from genetically modified organisms from genetically modified cultures simply because we know less about them. In addition, people are now focused on ecological farming, on everything clean and natural. They are just afraid of the lab. This is due to mistrust, people do not trust science itself, because there have been many cases of use, for example, of medical preparations that did not work and damaged health or their use led to death. They are afraid of people in white coats. The same applies to GMO organisms. It is much more difficult to explain to people that what has been in the laboratory is definitely harmless. People prefer organic food. In conclusion, the last thing: everyone is concerned about the concentration of these technologies and knowledge in large companies. University laboratories cannot bring to the market any product due to the high cost of security research, so some start-ups are being created that are acquired by large companies, it is the main hook, which can jeopardize entire areas of production. How can you minimize the social aspect of attitudes towards GMOs in the first place? There is such an experience. For example, in Europe a very good harmonious system of â€Å"coexistence† has been developed, which was fixed by European directives when the farmer himself decides which type of agriculture to use: organic, traditional or biotechnological. Accordingly, the consumer also has the right to choose those products that he wants and is ready to use.
