massive nuclear reactor that burns numerous amounts of hydrogen; and just like an actual nuclear reactor, hydrogen is the essential fuel in nuclear fusion reactions. The hydrogen in these fusion reactions fuse together to form beryllium, helium, and lithium atoms. “The temperature on the surface of the Sun is approximately six thousand degrees Celsius. While at its core, it is about a million degrees Celsius” (Solarsystem.nasa.gov,2013). The Sun, just like all other stars in the galaxy, is also…
The color a flame turns when burning a chemical compound depends on the metal ions the compound’s elements contain. What causes color to be shown is the excitement of electrons in an atom when heated, which makes them jump to a higher energy level. As the electrons begin to return to their original energy level, energy is released as light, coloring the flame (“Flame Tests”, 2005). And as energy increases, frequency increases, but wavelength decreases. The color each chemical turns the flame…
Introduction Have you ever felt sadness, guilt, or loss of interest for over two weeks of time? If so, you probably have one of the most common mental disorders in America today. Depression can come and go, but even with extensive research, no one knows exactly what can onset depression. Many people with depression need someone to notice their suffering before they will actually get help, and sometimes that call for help will be drastic. Anyone can have depression, but the symptoms, types, and…
There is a lot of negative stigma around the word mental illness. In particularly I will be talking about Bipolar disorder. Bipolar is also known as manic depression. It is a serious disorder that affect the brain. It is a very common disorder; In the united state alone, more than 2.3 million cases appeal yearly. Although the cause of is not known for sure. Studies shows that there are a few factors that can make some someone vulnerable to the disorder. The factors as follow: environmental,…
Scientist Contribution Significance Lavoisier (1743-1794) Antonie-Laurent Lavoisier was born on August 26, 1743 in France’s capital city, Paris. One of his major discoveries was the founding of the law of conservation of mass. This law states the weights of reagents and products are conserved through any chemical reactions. This is demonstrated through his combustion experiments. He pointed out that combustion requires air, since the reactants are weighed heavier than its products. This…
disorder, as addressed by Dr. Mark A. Frye, “… There clearly was greater benefit with lamotrigine compared with placebo in delaying the time of progression from subsyndromal to syndromal depressive illness. However, we found a greater benefit with lithium compared with placebo in delaying the time of progression from subsyndromal hypomanic or mixed symptoms to mania or a mixed…
The automobile market of nowadays is changing, a tendency toward hybrid and electric cars is taking shape. This shift toward hybrid and electric vehicles is supported by all sectors public, private, industrial and academic. In this essay we will analyze the case of a leading company in producing electric vehicles; BYD. First, we will start by examining the viability of EVs as an alternative of gasoline-powered vehicles, and presenting our vision of the future of electric car market. Second, we…
The Soviet Union’s takeover of Eastern Europe was interpreted by the United States as an attempt to spread communism around the world. The United States was highly against communism. The U.S., being a capitalistic run nation, felt worried for other nations who possibly could not afford fighting against the Soviet Union. Concerned that Greece and Turkey might be the next countries to fall to Stalin, President Truman announced the Truman Doctrine. This stated that the United States would give…
Why Children Work? The work of children can be helpful to the child, family, and community. Paid and unpaid child labor can support the family or it can provide the child with money. It is possible for children to continue their education, to benefit economically and socially, and to contribute to family income if they work limited hours in non-abusive conditions. However, such ideal work conditions are unequally available throughout the world depending on the country’s culture, political…
I read an assertion that stated, the existence of helium, lithium, and deuterium in the cosmos was brought into existence from the Big Bang. I was able to have faith in the claim, for the first neutrons created would have likely created elements with low atomic masses - known as Big Bang nucleosynthesis. A second…
