The Physics Of Thermal Energy - 1609 Words
Thermal Energy in Peanuts Kristin Guenev, Hannah Potter, Rebecca Fluegel At the ignition of a peanut, how much thermal energy is produced? The same energy that is emitted at the burning of a single peanut contains the same principles that heat our homes, cook our food, or why we feel cold in the winter and warm in the summer. Though much associated with temperature, thermal energy is not the same. If we were dealing with temperature in our experiment, we would have asked: What is the change in temperature of water when a peanut is burned? However, thermal energy is the potential movement of heat from one object of high temperature to lower temperature. When comparing a steaming cup of coffee, and an iceberg, the temperatures are exactly what they seem to be, but the thermal energy of the two objects are the direct opposite of what they are assumed. Sure, the coffee has more heat, but the iceberg has more energy. One of the reasons we chose a peanut, of all things, was the remarkable amount of thermal energy that it contains. Due to our experiment and the specific heat equation, Q = mcDT, where ââ¬Å"Qâ⬠is the heat flow in calories, ââ¬Å"mâ⬠is mass, ââ¬Å"câ⬠is the specific heat and ââ¬Å"DTâ⬠is the temperature difference between the two objects, we discovered that an average peanut can produce 45.54 calories, or 190.5 joules, which will further be explained. This conclusion of a single peanutââ¬â¢s potential energy was what attracted our group to theShow MoreRelatedThe Theory Of Heat : The Natural Sciences Span Over A Wide Range Of Phenomena1126 Words à |à 5 Pagesallowed to research these phenomena due to underlying connections between subtopics.

Essay about Lifes a Beach, and then... - 963 Words
I turned off the car and took a deep breath. Looking slowly up into the pink sky, I began to watch the golden sun go to sleep. The beach seemed deserted, quiet, but peaceful. I opened my door and put my feet out on the soft sand. I started taking my shoes off, then my socks. I threw them in the passenger seat, and then shut the door. I looked out over horizon of the lake and started walking towards the still water. With each step I took, I could feel the warm sand crunch between my toes. Then suddenly, a sharp rock, but not sharp enough to break the skin. Closer and closer to the calm water, I began sinking deeper in the sand. It was comforting, the silence, tranquility, and warmth of the faint sun. There is a slight breeze, warm, butâ⬠¦show more contentâ⬠¦When I opened my eyes, all the birds were gone except for one. The bird was like me. It didnt want to fly away; it wanted to stay there on that lonely beach and watch the sunset of a lifetime. No sound, just the wind blowin g thunderously through my ears. And the waves crashing down on the wet sand. It made the hair on my arms stand up and I got a chill, but I didnt move. I took another deep breath and started walking towards where the water meets the sand. With each step I took, the sand got cooler and cooler. Then, with a final step, it turned cold. My feet were in the cold water and sand. It was sudden, wet, but soft. The dark blue water drew back in. Thrusting violently, crashing everywhere, the lake threw its cool brisk body into my dry legs, scaring the lone bird away with its unique destructive sound. The wind started to pick up a little. It was extra cold on the wet spots of my body. The water was as black as silence, with only a slight reflection of the sun. I could not tell the lake was there. The sun took the lake with it, to share with someone else. I stood there for a couple more seconds, and before I knew it, the sun was gone. The colors became more independent as the shadow of the sun le ssened. Then, it was gone. Without trace, sound, or movement.

Political Changes in Europe Since the Fall of the Soviet Union Free Essays
In April 1986, Mr. Gorbachev began the perestroika, translation ââ¬Å"reconstructionâ⬠, which was to end the Cold War that effectively brought down the Iron Curtain. The split between West and East not only partitioned the world into two parts, but also divided the European family for over 40 years. We will write a custom essay sample on Political Changes in Europe Since the Fall of the Soviet Union or any similar topic only for you Order Now With the fall of the Soviet Union came many changes that affected much if not all of Europe. At the end of the Brejnev era , the socialist bloc was severely outdated and far removed from the contemporary world. The economy was in a shambles, independent civil society was largely in exile, and corruption throughout and within the state via the Communist Party had become legendary. In addition, the USSR had to devote an enormous portion of its budget to the military. On the international level, the USSR had lost many allies, because its social model proved to be decreasingly successful in its deceit, and the ill-fated invasion of Afghanistan (1979 ââ¬â 1989) did not help in any way. It was therefore necessary to undertake urgent measures, especially in countries where satellite totalitarian regimes were challenged and the USSR no longer had the support of local communist parties. The advent of Gorbachev to power marked the beginning of the reconstruction. His first step on his rise to power was the partial liberation of the press, also known as glasnost. The first free newspapers emerged and some major newspapers such as ââ¬Å"Novii Mir (New World),â⬠Argumenti i Fakti ââ¬Å"(Arguments and Facts) orâ⬠Moskovskie Novosti (Moscow News) changed editors. Books banned by the Soviet censorship began to appear in stores. Also, films which had been censored until this time were finally appearing on the screen. The policy change was also considerable. Under Gorbachev, 140 dissidents, victims of Stalinist repression, were honored and rehabilitated. From exile in Gorky, Sakharov, who condemned the war in Afghanistan ââ¬â was released. Several opposition political organizations emerged as a Democratic Union and in 1988 the first anti-communist demonstrations took place. Gorbachev, considering the difficulty and complexity of the political situation at the time, tried at any price to change the political elite in an effort to ensure reconstruction. Policy frameworksâ⬠began and brought fresh faces to power. ââ¬Å"Without ââ¬â partiesâ⬠(political parties that were not members of the Communist Party) were authorized to occupy important positions in state bodies. In addition, elections were introduced within the party to make elected officials accountable to its voters. Before this time, t he party presented a candidate for the post and members could only nod in approval. Despite all this progress, the USSR was unable to overcome the economic and social crisis that hit the country in the early 80s. The Soviet system was not adaptable by itself and reconstruction was doomed from the start. Gorbachev did not have the political capacity to push the desired reforms through. His strategy, in essence, triggered the collapse of the USSR, which was completely unexpected. Perestroika could not change the structure of the Soviet economy, and thus served as an obstacle to reforms. All means of production were under state control. In addition, factories managers and corrupt officials wanted at all costs to keep the economic system that afforded them considerable privilege, especially in a country where the deficit of consumer products was seen in everyday life. The political system, like the economy, rested on a foundation of lies. Political leaders from cities and regions fabricated domestic and foreign policy statistics, using propaganda, including the newspaper ââ¬Å"Pravdaâ⬠(Truth). This newspaper was later to become a symbol of Soviet exaggeration of the productivity of the communist state. The Soviet secret services were doing everything to prevent people from having information deemed undesirable; any foreign or independent press was prohibited. In launching his reforms, Gorbachev wanted to reform that which what was not reformable. Perestroika and glasnost had made the system fragile, because the lie was no longer there to blind people. Thus, in 1991 a political system that had seemed indestructible ââ¬â unbeatable, all but disappeared from the world political map. Perestroika was ultimately the determining factor in the fall of the Iron Curtain. The forces it unleashed, such as freedom of speech (glasnost), by Gorbachev inside his country had devoured the communist parties of Eastern Europe. That was also the case with the fall of the Berlin Wall and subsequent German reunification. The fall of the Berlin Wall was largely provided for by the green light given by Moscow. Without such approval, it would have been very probably a repetition of the ââ¬Å"coup de Pragueâ⬠of 1968, as the forces of the Warsaw Pact entered the Czechoslovakian capital to put an end to the democratic reforms of Dubcek following the Prague Spring. After the fall of the Berlin Wall on November 9, 1989, the reunification of Germany was inevitable. The non-intervention of Warsaw Pact forces during the fall of the Berlin Wall signaled the outbreak of the revolutions that occurred thereafter. Elsewhere in 1989 in Eastern Europe, democratic movements freed from the tutelage of Moscow out-punched Communism. This is the case in Romania with the fall of Ceausescu, Czechoslovakia and Poland with the resignation of the communist government and the start of negotiations between General Jaruzelski and the representatives of Solidarnosc. The policy of rapprochement between the West promoted by Gorbachev led to the collapse of the Warsaw Pact. Having neither the financial resources nor the political will to save this military alliance, the Soviets proposed in 1988 to repeal the pact against the dissolution of NATO. In December 1988, Gorbachev and Bush declared at a meeting in Malta that the Cold War was over. Immediately after the fall of communism in Europe, former satellites of the Soviet Union chose to join the unified European family and NATO. Chronologically, in the first half of 90 years, almost all the countries of Central and Eastern Europe (CEE) have submitted their applications to join the European Union and NATO. For these countries, membership in these structures is first and foremost a political symbol, to guarantee their freedom and sovereignty. European integration also meant the return of these countries into the European mainstream as equal partners and not merely as ââ¬Å"little brothersâ⬠, as was the case with the USSR. Long oppressed by a regime imposed from outside, these countries could finally defend their interests in the democratic framework that the European Union offers. Without perestroika, the world today would not be the same. It is mainly through this process that democratization has been set up in the Central and Eastern Europe and that Europe is no longer divided in two.

Great Barrier Reef Essay Example For Students
Great Barrier Reef Essay The Great Barrier Reef The Great Barrier Reef is the biggest group of coral reefs in the world. It stretches along the coast on the north-east part of Australia. It is called the Great Barrier Reef because it creates a barrier between the Pacific Ocean and the coast. The Great Barrier Reef is a scattering of thousands of individual reefs. The reefs is on the World Heritage List made by UNESCO, because of its size and its many different plants and fishes. The reef lies in the Great Barrier Reef Marine Park, the worlds largest marine park. It has an area of nearly 350 000 square kilometres. The reef region is 260 000 square kilometres. The reef region is a popular tourist attraction because of its warm climate, sandy beaches, colourful wildlife, tropical islands and ideal conditions for water sports. Location and size The Great Barrier Reef stretches north and north-west from Gladstone, Queensland, to a point in the Gulf of Papua. The Great Barrier Reef is longer than 2000 kilometres a nd consists of nearly 3000 different reefs. An average reef is about 110 square kilometres in area. The area that The Great Barrier Reef lies in has relatively shallow waters of about 40 metres deep. Marine Life The Great Barrier Reef consists of billions of smal animals called coral polyps and plants called coralline algae. The coral reef is built up by dead corals, with a thin outside of living corals. A coral reef includes many species of corals, such as staghorn coral, brain coral, honeycomb coral and mound coral. Almost 1500 of 3000 kinds of fish known to live in the seas around Australia are found in the reef region. Angelfish, cod, manta rays, mackerel, butterfly fish and surgeon fish all live in reef waters. Other animals that live in the reef waters include crabs, shrimps, crayfish, sea urchins, sea stars, sea cucumbers, soft corals, sea fans, sponges, sea anemones and worms. Physical features Experts think that parts of the Great Barrier Reef could be as much as 18 million years old. But the most of it have developed over the last 2 million years. The reefs on the top are only a few thousands years old, but most of these reefs are built upon a foundation of older reefs. Sea level was more than 130 metres below todays level about 20 000 years ago. The existing reefs were at this time limestone hills rising from the plain. The sea level started to raise about 18 000 years ago, and the hills were covered with water. Corals began to grow again. The old reefs often provided the most suitable foundations for this new growth. When the land was covered by the rising sea, a number of mountain ranges were cut of from the main land to become continental islands. There are 616 islands in the reef region. Climate The climate of the Great Barrier Reef varies. In the north there is tropical conditions and high humidity and a wet season around January. In the south it is cooler, subtropical to temperate conditions. The water temperature in the south seldom falls bel ow 20 C. BibliographyfgsdafsfsfsafPsychology Essays
