nuclear fusion reactor‚ but we could be relying on them for power sometime in the next 30 to 40 years. Nuclear Fusion is created by forcing deuterium (D) and tritium (T) together‚ when forced together their nuclei fuse and then break apart to form a helium nucleus and an uncharged neutron. Most of the excess energy is contained in the free neutron. Fusion occurs at a very high temperature (greater than 100 million Kelvin). At this temperature the deuterium and tritium gas mixture becomes a plasma

not-very-luminous celestial body having a mass between 1028 kg and 84 x 1028 kg). A Newborn Star: When a temperature of about 27‚000‚000°F is reached‚ nuclear fusion begins. This is the nuclear reaction in which hydrogen atoms are converted to helium atoms plus energy. This energy (radiation) production prevents further contraction of the star. Young stars emit jets of intense radiation that

Chapter 6 – Properties of gases lecture notes 1. Gas phase Gases have neither definite shape or volume 1) volume changes with pressure 2) volume changes with temperature 3) gases are miscible 4) gases are generally MUCH less dense than liquids 2. Atmospheric pressure 1 atm = 760 torr (mm of Hg) F= ma F = force m = mass a = acceleration P = F/A - ma/A P = pressure

Fusion in the sun ‚1 second ‚ 600 million tons of hydrogen are being converted into helium‚ this reaction releases tons amounts of heat and energy. The process of fusion in the sun is known as The proton chain. The sun starts with protons and through a series of steps ‚ it turns into helium. When this is happening something called plasma is being formed. Plasma is being ionized. The sun is so hot. Really hot but all of the heat and light coming from the sun comes from the fusion process happening

Billy the Bully I always hated school. I didn’t mind learning new things‚ or seeing my friends‚ or doing math and writing papers. In fact‚ I liked every one of those things. I hated school because of Billy‚ a mean‚ big‚ awful kid who bullied me every day. Once when I was in 2nd grade‚ he jammed a pencil right into my arm. “Ow!” I yelled. “Why did you do that?” “Because I hate your stupid red hair‚” Billy replied. I said‚ “What do you have against people with red hair?” “Because‚” Billy said‚ “people

This song was originally written in 1983 by the German band named Nena. As well as its orginal recording in German there is also an English version written by Kevin McAlea which was released shortly after the worldwide spread success that the original had. This English version was not in fact a direct translation of the German lyrics and has different meanings in its lyrics. The broad ideas covered in the song is that of an anti-war protest focusing on nuclear war. The genre that this work falls

The universe is a canvass of innumerable objects such as planets and stars. If you lay on your back on a warm summer night I would not doubt that you would be enchanted‚ enticed‚ and bewildered by the luster and mirth of all the stars you may even just wilt on the thought of how large they are. If you browse the sky regularly some notable features you you might know is the tactful North Star and the puny Little Dipper.
