Chemistry Flame Test Lab Report Essay Example

Chemistry Flame Test Lab Report Essay Example Chemistry Flame Test Lab Report Paper Chemistry Flame Test Lab Report Paper Test Lab was an experiment designed to show how elements react when heated. This Lab attempted to prove that when electrons are excited and then calm, they emit a color specific to the element. This test showed that there is a direct coloration between the heat energy being expelled and the movement of electrons from one energy level to the next. When the atoms of a gas are excited, in this case by heating, their electrons are able to move from their ground states to higher energy levels. The electrons that move are considered excited. As they return to their ground state, the electron emits energy. The energy emitted corresponds to a particular wavelength, and therefore produces a particular color of light. If a excited electron drops one energy level, Its color will be red. If it drops 2 energy levels, it will be orange yellow. 3 energy levels produces greenish blue light and 4 dropped energy levels produce violet light. The amount of energy levels electrons move up after being heated relates to the color of light it produces.

Music and Color (which ones positively affect employees,which ones Essay

Music and Color (which ones positively affect employees,which ones negatively affect them) - Essay Example â€Å"Music in the workplace promotes positive mood, sense of team, improves alertness and can lessen the event of accidents† (Marshall 2007). There is a mood threshold beyond which productivity rapidly decreases. The high value attributed to the use of light music rather than classical music partly reflects the generally low level of effectiveness achieved by classical music. â€Å"Music â€Å"motivates workers, decreases boredom and leads to increased productivity perhaps because people work in time with the beat† (le Roux 2005 cited Marshall 2007). Music also means that people can learn more effectively and work more creatively, and hence sustain stress more effectively. Ability to work together harmoniously, or cope with unforeseen circumstances, points towards people feeling healthy, having a sense of well-being, having high morale and being able to accept more responsibility. In general, music allows people respond to work situations more positively. (Goodman 200 7). Similar to music, colors have great impact on employees and their mood. Pronounced colors have a negative impact on productivity increasing distress, low self-esteem and aspirations (Birren 23). In the long term, dark colors can have secondary effects on health and that visible flickering can have profound effects on the human nervous system. The trend towards darker colors is unlikely to affect health adversely, and may indeed be advantageous. The trend could have negative consequences for health if it were shown that the increasing levels of ambient light at night affect circadian rhythms. Improvements in brightness and the evenness of spectral power may be beneficial. In particular, the move towards a greater use of green, yellow and white is likely to be good for both health and performance. Intervention to ensure a healthy working environment should always be the first step towards improving productivity and work

Antigone by Sophocles and Ancient Greek Civilization Essay

Antigone by Sophocles and Ancient Greek Civilization - Essay Example Creon fails to acknowledge her plea and is condemned to death. Creon had presented the rule that the person who would bury Polyneices would be subjected to death. This is because he had termed him as an intruder and a murderer to his predecessor Eteocles in the battle for the throne (Sophocles 2) Creon had made the ruling that the body would be left to rot instead of a proper burial, a ruling that Antigone defied. Unlike his brother, Eteocles had been given a proper burial, and the angry Antigone sought to place her brother’s body to rest in peace. The actions of the woman to disobey his ruling angered the king and sentenced both Antigone and her sister Ismene to death (Sophocles 1). Consequently, Creon’s son Haemon pleaded with his father to overturn his ruling because he had been engaged to Antigone, and had not wished to lose his fiance. Creon failed to adhere to his so wishes, but releases Ismene banishing her from the land. Furthermore, the prophet Teiresias warned the king against defying the gods wishes to bury Polyneices and warning him of a tragedy. The events witnessed Theban citizens recite a chorus that reminded the king that the prophet had never been wrong and that, his ruling that he would lose his son would happen. He hurriedly changes his mind for fear of the misfortune and performs a proper burial ceremony to bury Polyneices body (Sophocles 9). On the attempt to free the imprisoned Antigone, he is too late to avoid tragedy and finds a dead prisoner bringing more sorrow in the death of his son who chose to stab himself. The heartbroken Creon returns to his palace to meet an added misfortune in the death of his queen Eurydice who, chose to kill herself on the news of her son’s death. The story teaches on poor leadership skills and the consequences of defying the wishes of the gods. Democracy in Athens The reek had been a barbaric tribe that had migrated from the European nation to Aegean in the quest for a new land. The inte raction led to the integration of their traditions and those of the natives that they had encountered in the region. After settlement within the region, the individuals became influenced by Crete establishing an organized civilization by 1600B.C. known as Mycenaean civilization (Lewis 46). The Greeks adopted the trend from the Babylonians and Hittites to incorporate found civilization and practices to their own creating a different civilization form. Greek civilization had been created to present an organized system that had not failed to achieve organization. The states had been minute consisting of contained towns built at the center of a higher ground with temples created to present a civilization that defined the state. The Greek created fortress and temples that presented significant importance to the Greeks and a center of unity. The example was presented in Athens that had been termed the city of Athena the goddess who had been charged with the town and offered protection to the members. Democracy stretched in Greek to accord participation of all the members developing a term, polites in their language to define the citizens. The Greeks had been organized in city-states lacking a universal empire and protected through an extended land and sea. With the lack of an organized government, the states did not possess the value to employ professional forces that would offer the needed protection. Brave men who had chosen

It all started in the summer of 2007 when a crisis hit the U.S., and because of the huge government interventions that were made, the U.S. and most European countries got into a recession. The EU crisis was also caused by big debts made mostly in Spain and Italy, before 2008. The private sectors (companies and mortgage borrowers) who were taking out loans were the main reason for this crisis. There was a decrease in the interests rates in southern European countries when they joined the euro and that resulted and caused the countries to go into a huge debt. This had negative effects on the financial markets, a slowing down of the economic growth in the industrialized countries, and impacted the European labor markets. After the Second World War the unemployment rates in Europe were already low, and with the crisis the percentage of the unemployment rates just increased in the following years. All of this was due to different problems and occurrences that they were facing such as; the two oil price shocks, the decrease in the production growth, the disinflationary policy of many Central Banks, and so on. This recession resulted in very high unemployment, and the increase in unemployment during that period was made by using some internal measures (such as flexible working time arrangements, temporary closures, etc.) but the unemployment was not equally shared between the different groups of people (the largest differences occurred due to the sex, education, age, etc.) but at the end these measures only delayed the process of significant labor unemployment, it didn’t help the situation go back to how it used to be before the crisis. The labor force of a population is involved with the people who are employed and unemployed. The Inte... ... face many problems, the European labor market was affected by this crisis as well, and there were many other problems that were faced during this hard period. The EU’s plans for the future are to minimize the job losses and prevent unemployment, improve job creation, and to recover the economy in a full and stable way. In order for them to make this happen and in order for them to improve and develop the flexibility of the labor market and in order to raise the labor supply, they made some cuts in the income taxes, improved the access to non-standard forms of work, redirected the active labor market policies, and similar activities like these were made. But even though the EU crisis has influenced the European labor market and has created many problems and struggles with unemployment, in the past couple of years they managed to increase the unemployment rate by 2%.

Magnanimous Pharash

The Magnanimous Pharaoh Forever Lives in Me On the morning I was making plans for my summer break, I got a package from home in about a 6 inch 4 mail box. I ran to my room in excitement to unwrap my new gift. Surprisingly, I saw a blue and white hardcover textbook. I sighed in disappointment it was the Kaplan textbook I had to study for my SAT exams. At night, when I was about starting to read I was so uninterested and disturbed that I started flipping through pages. Not long after, I felt dizzy and went to bed.That night, I had a dream, I saw myself in a completely new lifestyle, attitude, behavior and most of my rinds had same transformation as mine. I wonder how this rarely believed dream came true and made me a wonderful young man I am. Every morning in my brick hostel, in my clean and small room at the four walls of Immaculate High School on the outskirt of Kirkwood in Lagos, Nigeria. Before I hear the six loud bells of the tower when the sun ray penetrates my window, there's a knock on my door. I hear a shrill and high pitched voice say, Get up! Get up! A slender man in his daily stripped khaki pants with a glass of cold water stands tall over me. I suspect the glass of water could e used to drench my shirt rather than quench my thirst if I fail to wake. This is Pharaoh, 45 years old, house helper, sweeper, caretaker, and the only person to know where I keep my letters from my girlfriend. He was Just a man all students believed was either a high school dropout or a douche that had no word of encouragement or could be of influence and importance. He is like a precise robot programmed to keep my life and that of the other seventy other boys in my boarding house in order.For five years, I saw him every day cleaning and washing. It is a mystery to me how someone who lives such a mundane life sill greets me with a flash f his 31 teeth overtime I cross his path. Growing up, I never felt respect and I was not ready to give it back, my disregard about life didn't make me see the exigency of being a benevolence to people and life my tender mind was only bothered about the positive aspects of life having fun, hanging out with friend, play video games, and surfing the internet were my priorities.I was not ready to be pestered by the negativity of life all I wanted was pleasure, I felt no remorse about being rude and disobedient I thought money could solve every difficulty and problem. I ponder recurrently to know what the cause is. Was it my parents? Should I have not be nurtured as a rich kid while growing, or was I influenced by school mates. I thought of all this in my early teenage years. I wonder how a minor incident could be of transformation and totally put a stop to my way of living in my early teenage years.Few months before spring break, I had a terrible night tossing and turning before my SAT exam. Words swam in my head as I pondered the difference between allusion, illusion, and elision. The next morning Pharaoh looked more tense t han surprised to see me awake. He asked me much like my mother would, â€Å"What happened? Why do you look so worried? Has the sun risen from the West? On filling him on my war with words, he smiled and assured all would be fine. It was the first time I heard him speak, and it was a revelation. I didn't realize that this man was more than Just a â€Å"come and go' machine.The fact that he empathetic with me like my mother convinced me that he was going to influence my life for the better and make great amends to my way of living. That afternoon when he came to clean my hostel room, I inserted a #100 naira note into his hand and requested him to get a packet of chips. He frowned and frowned even more. I snatched back the note and ran to the dining hall for a barely edible breakfast. I felt bad for having crossed the line. I should have respected the school rules, I wished that he would not complain about my transgression.To my astonishment, that afternoon, I saw not one but two pac kets of chips lying neatly on the pillow. He grimaced, displaced his 31 teeth, and walked out of the room. I was taken aback, I couldn't believe that a man with a large family to support and a meager income to do it with had generosity to fulfill my petty temptation. Many chips later, I realized that he didn't grudge me the chips; he was simply against taking money from me. He found Joy in giving and he had great pride in himself. Secretly, I envied him.For he had found the contentment most people spend their live chasing. I envied him because he smiled all through the day. I learned from his example, that there are some things money can't buy. Contentment and generosity are Just two of them. Pharaoh may not be a Mahatma Gandhi or a Nelson Mandela that might have influenced a lot of people due to their reputable positions, and encouraging lifestyle, but Pharaoh lifestyle as an average living Man though he wasn't educated, rich or popular but he was till generous with the little he h ad and was contented with what he had left.He was able to influence the life's of other teenage boys in my high school dormitory through his simplicity and humility and made remarkable changes in our lives, my parents were happy to see the new me and lauded him for being a great influence to my life and that of my school mates. Pharaoh may not have the ability to do great things, but I saw the greatness to have the ability to do small things in him.
