Tri-State Water Wars: Impact on Metropolitan Atlanta’s Future Growth Es

Tri-State Water Wars: Impact on Metropolitan Atlanta’s Future Growth â€Å"Whiskey is for drinking. Water is for fighting.† - Mark Twain Metro Atlanta is on a collision course with reality – and the shock of this collision will have profound political and economic implications for future growth throughout the Southeast. The core problem is that Atlanta’s runaway growth will soon outstrip the available water supply (Corps, 1998). And if Atlanta continues to increase its water consumption until the maximum limits are reached, the effects on downstream users will become catastrophic, both economically and environmentally. Without multi-state agreements concerning changes in usage patterns, this could bring about intervention by the Federal courts that would effectively halt Atlanta’s development until the usage disputes were resolved. By comparison, some western states water lawsuits have lasted for decades, typically freezing usage patterns â€Å"as is†. (Barr, 1999) The southeast can ill afford to have Atlanta – the region’s single largest engine of economic growth – brought to a standstill because of this issue. The root cause of the entire regional problem is the combination of Atlanta’s high growth and an inadequate water supply. No US city as large as Atlanta is founded on a river as small as the Chattahoochee. (NY Times) If Atlanta were the size of Birmingham, there would be no crisis whatsoever.

Heat of Combustion Lab Essay

There are many fuels in the world and we use fuel everyday in our life. However some fuels are very useful and some are not. Usually useful fuel means the fuel that is very efficient in a small amount. To know the efficiency of each material, we measured the changes of mass and temperature when we burn them. And we calculated changing energy by using the equation that we learned in the class by using our measurements. And we calculated the heat of combustion to know the efficiency of the material. We also used the data booklet value for the standard enthalpy of combustion of each material to get the errors in our experiment. Errors in our experiment were usually over 20 percent which is quite large. Before we heated the water, we made the temperature of water below than 10à ¯Ã‚ ¿Ã‚ ½C with ice to see the changes of temperature more efficiently. If we just heated it in normal temperature such as 20à ¯Ã‚ ¿Ã‚ ½C, we couldn’t see the changes of temperature well, and it could take more time to heat it. We also measure the changes of mass of material to see how much we burned. We put some ice in the water to make the initial temperature of water as lower than 10à ¯Ã‚ ¿Ã‚ ½C. When the temperature decreased up to 10à ¯Ã‚ ¿Ã‚ ½C, we took out ice from the water. After we took out the ice and fill the cylinder up to 200ml of water, the temperature was higher than 10à ¯Ã‚ ¿Ã‚ ½C because the temperature of the water changed very quickly. We measured the temperature of water and then we hang the tin can on the hanger, so the temperature might increased again during we set up all the experiment systems. So we should measure the temperature of water when we set up all the things. For example we should measure it after we turn the light on the candle wax and hang the tin can on the hanger. We measured the final temperature to see the changes of the temperature. We blew out the candle when the temperature reaches 35à ¯Ã‚ ¿Ã‚ ½C, and we measured the highest temperature reached as the final temperature. When the temperature reaches 35à ¯Ã‚ ¿Ã‚ ½C, we quickly blew out the candle. However we are not accurate as the machine so we might didn’t blow out it when it reaches exactly 35à ¯Ã‚ ¿Ã‚ ½C. Also it was difficult to measure the highest temperature of it after we blow it out. Even though we kept watching it, the temperature changes so quickly, so our measurements are not correct 100%. In our experiment we didn’t measure the mass of tin can. If we measure the mass of it, we could get more precise measurement compare to the standard enthalpy of combustion. Our errors are quite large, so I think one of reason is that we forgot the measure the mass of tin. So we should study and think more about the experiment before we do it. We could calculate how much heat we got by adding the changing energy of water and the changing energy of the tin can, if we measured the mass of can. At the end of the experiment, we measured the mass of candle to know how much of them were burned. During and after we blow out the candle, some of liquid were might evaporated. Such as ethanol and butanol are volatile liquid, and the fact that the lamp was hot indicates that some of it would have evaporated. So they are burned and evaporated more after we measure the temperature. Another fact that we should consider is that not only the water was being heated, but also the thermometer, stirring rod and the tin can were also being heated. We should consider that they were also heated, so we should measure how much heat were used to heat them. Also some other heat would have been lost round the sides of the tin can, and from the water to the atmosphere. Due to our room temperature are different from the temperature of water. The good thing that we did in our experiment is that we made some space when we set up the large metal can to surround the candle. As we make some space under the large can by putting some flat cylinder under the can, the candle burned more quickly and well. If we didn’t make the space for it, air might stuck in there so it would take more time to reaches up to 35à ¯Ã‚ ¿Ã‚ ½C.

Context for Christian Moral Reflection Reflecting on our morals, as Christians, can sometimes be a difficult task. As Christians, we all hold many morals and beliefs on specific issues and happenings that occur in our world. We are surrounded with different ethical concerns. How we approach these issues depends on our morals and ethics. As Christians, we gather information on our morals through passages and teachings that occur in the Bible. The Bible is full of important stories that can be interpreted and applied to our every day lives and common issues in the world. McCarthy states that, â€Å"The primary role of Scripture in moral discernment is to open our lives to seeing and experiencing [†¦]† (McCarthy, 44). The Scripture can give great insight to how to live a moral life and also reflection on our moral beliefs. From Scripture, we can gather much information on how to be moral beings. The scripture includes many different stories that were told by Jesus that offer messages on how to live ethical and moral lives as Christians. Almost every passage in the Bible can be interpreted as delivering an important ethical message. For example, the Ten Commandments provide a list of rules to follow in order to reach the kingdom of Heaven. The Ten Commandments play an extremely significant role in our journey in becoming the most moral and ethical people we can be as Christians. Also, the Beatitudes provide another list of ways for us, as Christians, to continue our path to heaven and being moral individuals. Although these passages provide lists on ways to be good people, they also require prayer and studying in order for the reader to receive the most important message from the readings. As stated before, there are several important passages from the Bible that give significant information that can be used for moral reflection. One of the most important of the passages in the Bible is the Beatitudes. The Beatitudes are a list of bless ings and lessons from Jesus that were recorded so that we could learn from them and be better individuals. The Beatitudes are most significant for several reasons. Although the Bible is not necessarily always easy to comprehend and understand, the Beatitudes are basically straightforward. They provide a simple list that can easily be followed so that we are able to live happy lives. We are happiest when we follow the rules of Jesus and live as moral human beings. There are eight Beatitudes that are recorded in the Gospel of Matthew. The Beatitudes are basic and simple and easy to learn from. For example, the eighth Beatitude says, â€Å"Blessed are those who are persecuted because of righteousness, for theirs is the kingdom of heaven† (Matthew 5:10). In other words, Jesus is delivering the message that anyone who is willing to die or be persecuted because of his or her morals and beliefs will be rewarded and able to go to heaven. This is just one example of how the Beat itudes deliver basic messages on how to live moral lives. From the Beatitudes, we can gather lessons and information on how to lead better lives. Through examining the works of scripture, we can learn a great amount about our ethical and moral beliefs as Christians. McCarthy states that, â€Å"[†¦] Scripture is shaped by and continues to shape the worship of the church [†¦]† (McCarthy, 21). The scripture and bible provides great insight into how we should approach ethical and moral issues. Most specifically, the Beatitudes provide a list of simple rules to follow as Christians. The most significant context for Christian moral reflection is the scripture, as many people have passed it on throughout the years so that we, as Christians, can learn from the stories that were told by Jesus and his earliest followers. Without scripture and the traditions provided in the passages, we would have no guidance of moral thinking and ethics. Don’t waste time!
