The Definition of BRIC and BRICS

The Definition of BRIC and BRICS BRIC is an acronym that refers to the economies of Brazil, Russia, India, and China, which are seen as major developing economies in the world. According to Forbes, The general consensus is that the term was first prominently used in a Goldman Sachs report from 2003, which speculated that by 2050 these four economies would be wealthier than most of the current major economic powers. In March 2012, South Africa appeared to join BRIC, which thus became BRICS. At that time, Brazil, Russia, India, China and South Africa met in India to discuss the formation of a development bank to pool resources. At that point, the BRIC countries were responsible for about 18% of the worlds Gross Domestic Product and were home to 40% of the earths population. It would appear that Mexico (part of BRIMC) and South Korea (part of BRICK) was not included in the discussion. Pronunciation: Brick Also Known As: BRIMC - Brazil, Russia, India, Mexico, and China. The BRICS countries include more than 40% of the worlds population and occupy over a quarter of the worlds land area. Brazil, Russia, India, China, and South Africa together are a powerful economic force.

Enthalpy Definition in Chemistry and Physics

Enthalpy Definition in Chemistry and Physics Enthalpy is a thermodynamic property of a system. It is the sum of the internal energy added to the product of the pressure and volume of the system. It reflects the capacity to do non-mechanical work and the capacity to release heat. Enthalpy is denoted as H; specific enthalpy denoted as h. Common units used to express enthalpy are the joule, calorie, or BTU (British Thermal Unit.) Enthalpy in a throttling process is constant. Change in enthalpy is calculated rather than enthalpy, in part because total enthalpy of a system cannot be measured. However, it is possible to measure the difference in enthalpy between one state and another. Enthalpy change may be calculated under conditions of constant pressure. Enthalpy Formulas H E PV where H is enthalpy, E is internal energy of the system, P is pressure, and V is volume d H T d S P d V What Is the Importance of Enthalpy? Measuring the change in enthalpy allows us to determine whether a reaction was endothermic (absorbed heat, positive change in enthalpy) or exothermic (released heat, negative change in enthalpy.)It is used to calculate the heat of reaction of a chemical process.Change in enthalpy is used to measure heat flow in calorimetry.It is measured to evaluate a  throttling process or Joule-Thomson expansion.Enthalpy is used to calculate minimum power for a compressor.Enthalpy change occurs during a change in the state of matter.There are many other applications of enthalpy in thermal engineering. Example Change in Enthalpy Calculation You can use the heat of fusion of ice and heat of vaporization of water to calculate the enthalpy change when ice melts into a liquid and the liquid turns to a vapor. The heat of fusion of ice is 333 J/g (meaning 333 J is absorbed when 1 gram of ice melts.) The  heat of vaporization of liquid water  at 100 °C is 2257 J/g. Part A:  Calculate  the change in enthalpy, ΔH, for these two processes. H2O(s) → H2O(l); ΔH ?H2O(l) → H2O(g); ΔH ?Part B:  Using the values you calculated, find the number of grams of ice you can melt using 0.800 kJ of heat. SolutionA.  The heats of fusion and vaporization are in joules, so the first thing to do is convert to kilojoules. Using the  periodic table, we know that 1  mole of water  (H2O) is 18.02 g. Therefore:fusion ΔH 18.02 g x 333 J / 1 gfusion ΔH 6.00 x 103  Jfusion ΔH 6.00 kJvaporization ΔH 18.02 g x 2257 J / 1 gvaporization ΔH 4.07 x 104  Jvaporization ΔH 40.7 kJSo the completed thermochemical reactions are:H2O(s) → H2O(l); ΔH 6.00 kJH2O(l) → H2O(g); ΔH 40.7 kJB.  Now we know that:1 mol H2O(s) 18.02 g H2O(s) ~ 6.00 kJUsing this conversion factor:0.800 kJ x 18.02 g ice / 6.00 kJ 2.40 g ice melted Answer A.  H2O(s) → H2O(l); ΔH 6.00 kJ H2O(l) → H2O(g); ΔH 40.7 kJ B.  2.40 g ice melted

No Topic - Assignment Example So after some warm hugs and goodbyes I leave my city and shift abroad. Initially it is a bit difficult for me as it is a completely new surrounding, but gradually I start to get the taste of it. We are still in touch with each through phone calls and social media. Social media being so popular these days that it has almost created a virtual world for us where most of us like to live their lives. It does not make you feel that you are away from your near and dear ones. (Sherry Turkle, Alone Together) So it really helps me to be in touch my cousin and share my experience out here. Gradually my work pressure starts increasing and I get to spend lesser time online. As a result I don’t get enough time to sit and chat with my cousin online. He does expect it from me but does not complain. It has been around 3 months now that I have been situated here. Gradually our bonding is becoming distant. One Sunday I sit with my laptop and feel like having a chat with my cousin as it has been a long time. I check my inbox and find that my cousin has written me after a long time. I am all excited and happy. I start reading the mail only to get the shock of my life. He says that he missed me so much that he got a robot with my name and programmed it like me. In sense the robot likes what I like and has the same dissimilarities as mine. It is true that robotics is actually replacing humans in many ways like people use them to sweep the kitchen floor, take care of our aging parents, and provide us with reliable companionship. (Jonah Lehrer, â€Å"We, Robots†) But it is still hard to replace a complete human being. My cousin now spends most of the time with a robot that he calls by my name. Not that I am offended with this whole reaction of his. I am kind a shocked and deeply hurt inside. I always used to feel that I was that once special brother for my cousin and he used to love me that way but today it has completely changed for

Supermarket Observation PowerPoint Presentation Example | Topics and Well Written Essays - 500 words

Supermarket Observation - PowerPoint Presentation Example This trend follows for the various product brands. After the energy drinks come the juices. First one meets brands that boast of being organic and natural and those that are synthetic come after. The products are arranged such that single pieces of the product appear at or around the eye level. The pieces are arranged very close to one another and in fact touch against each other. The bigger containers of soft drinks are placed closer to the ground while those that are packed in many units are placed on higher shelves. As one traverses the aisle, the product prices keep changing depending on product, brand and size. The aisle starts with expensive products gradually introducing cheaper products and then ending in more expensive products. Yet again, the medium sized products which are moderately priced by brand are placed on the middle shelves. Given that many people tend to be attracted to goods placed at the middle shelves or at eye level, many product brands tend to be featured therein. Products that are middle sized or that are grouped in small units are positioned in the middle shelves. Smaller units and extremely large units of products are placed on upper and lower shelves. Middle sized products are thus more easily accessible to the potential buyer. The end caps contain goods that have closer expiry dates. The products featured therein are not quite much of a bargain. Most of the products featured in the end caps were full priced and could have been placed there to highlight their presence in the supermarket. Considering the arrangement of products as observed in the supermarket, it is beyond doubt that the aisle is arranged to offer the potential buyer utmost convenience as noted by Consumer Reports Magazine (par 1). Yet again, the aisle is arranged so as to lure the potential buyer into spending more than they had actually budgeted for as they have to walk longer distances to access the products that they would

Leadership reflection Essay

When I think about leadership, I never realized how important it is to critically analyze and reflect on how true or authentic you are as a leader. When I think of myself in a leadership position, at that moment I do not critically analyze how I am performing as a leader. I am caught up in my own world worrying about how people portray me as, are they willing to follow my lead? Am I appropriately dressed for the occasion? or just simply do they like me? I think these are the worries and insecurities that get in the way of me analyzing my true leadership skills. There are also several insecurities that get in the way of me engaging in true, authentic self reflection. One of my major fear/roadblock is trying to be a person I am not; in other words not being true to myself. Trying to live up to an expectation, whether around family or friends, there is a certain pressure or a legacy you are trying to keep that gets in the way of truly reflecting. It doesn’t matter if you have failed or not, it’s that constant reminder or you are trying to convince yourself that you can be that person your family or friends want you to be. I think personal reflection is crucial for leaders. I believe that in order to increase a leader’s competence, leaders have to continuously grow, learn, and reflect. In order to do that, you have to be true to yourself. In high school, I used to teach young children at a Hindi school every Sunday. Being in that environment and seeing how much of a positive impact I have on these young kids inspired me to lead in other aspects in my life. Having the opportunity to shape and mold these children into great role models, really gave me an insight on how important it is to have a role model/leader to look up to. That experience really sparked my interest in becoming a leader. I think being able to directly impact someone’s life for their betterment is empowering. Overall, I think all leaders are committed to make their group, organization, company, etc. a better place. As I begin to speculate what makes me who I am that gets in the way of me exercising my leadership skills effectively, a few things come to mind. The first thing, again, it is my fear of turning or becoming into someone I am not without me realizing. I know in order to be a good leader you need to be a good follower. I fear while following, I follow a person who leads me to be a person that I am unhappy with. I think with that issue also comes a problem with trust. I should trust the person I am following and when I don’t understand, question to understand why things are done a certain way. Like the cadet said,† Some of the most prevalent barriers I notice in myself are: fear, desire for acceptance, desire to make everyone happy, not willing to take risks and previous ideas of what leaders should do and how they should act† are the same barriers that I face being a leader. Along with those, I have a fear of being left out. It is crucial to identify these barriers and be aware of them so you can slowly try to overcome them and not let them get in the way of you being an effective leader. View as multi-pages
