Richardson with colleagues Osheroff and Lee, nevertheless, points out the essential features of ‘helium’ and the reasons which are worth startling the public to the extent of agreeing that expensive costs be imposed on helium for the sustenance of MRIs, fiber optics, rockets, and other machines that hold special vitality in supporting human lives and activities. Where does helium come from? (in geographical, political and economic terms, as much as the chemical origins). Basically, Sun is the primary source of helium, one of the most stable elements, which is yielded through hydrogen fusion reactions in the solar system whereas on Earth, the radioactive decay of massive elements which are chiefly thorium and uranium over billions of years is found to cause helium formation beneath the Earth’s surface. Along with natural gas, the helium produced exudes out of large rock cavities under low pressure into the atmosphere which has approximately five parts of helium per 100,000 parts of air (Lansing, 1995). In 1868, spectrometer was first used to examine the Sun’s chromospheres during a solar eclipse in India where the resulting spectrum confirmed quantities of hydrogen including yellow stripes which were alleged to characterize sodium element. Unconvinced by the initial hypothesis, French astronomer Janssen further investigated on the matter and was able to disclose the truth about the stripes as beyond the traits of sodium but were most likely part of an unknown element’s identity. On a separate intensive research conducted by Lockyer and Frankland, Janssen’s results proved that due to its ‘bright yellow stripe’, the element could not have originated from the earth after which Frankland proposed to call it “helium” coming from the Greek word “Helios” meaning Sun. Similar findings were revealed through a range of spectra of other stars that comprised the yellow stripes whereas Palmieri observed them in gases erupting from Mt. Vesuvius back in 1882. It was not until 1895 that the studies of helium became more meaning when Sir William Ramsay treated a Norwegian ore (cleveite) with acids which yielded evolution of helium gas. Hence, the appearance of the yellowish streak in the experiment marked the certainty that on our planet, helium does exist. After nearly two decades, around the same time radium came to be known, scientists had undergone another batch of efforts that would lay foundations for an understanding of helium as a radioactive substance (Helium, History). Geographical findings indicate that the United States, specifically Texas, makes the world’s largest manufacturer of helium despite the valuable presence of helium extraction facilities in Algeria, Russia, and China. Being distilled from the natural gas that contains appreciable quantity of uranium and thorium to undergo radioactive decomposition, the helium formed is normally derived from rare circumstances of alpha-particle capture occurring underground at considerable depths (Deakin, 2010). Helium is opulently recovered from a region in Amarillo, Texas or the Texas panhandle within a perimeter of 400-km radius and this accounts for a major resource amount that sustains different parts of the world with their helium requirement (Edwards, 2004). Colorado, Kansas, and Oklahoma are also states of origin responsible for contributing small percentages of helium throughout all nations (ScienceDaily). What are the major uses of helium and why are existing reserves irreversibly declining? Several applications of Helium has have been made possible due to the element’s distinct chemical and physical properties such as low boiling point, low ...Download file to see next pagesRead More

Antares has a size of about 2000 R. The Mv for these stars is – 5 (p. 143). 2). A star is born from the thin gases of space. When a star is born, there is normally a large cloud of gas and dust. The thin gases of space are known as the interstellar medium ( p. 162). When enough hydrogen is compressed through the gravity of these stars, hydrogen fusion is achieved. In the center core of these stars there is a helium core. A teaspoon of mass of helium from the center of a star would weigh more than a ton. When enough helium...

.... This collapse is usually triggered by a shockwave from a nearby supernova or expanding planetary nebulae.  As the cloud contracts the rotation will become faster and it will break up into individual clumps. If these masses are big enough the density and temperature in the core will become high enough so that nuclear fusion can start. Hydrogen will be converted into Helium. The "burning" of Hydrogen produce a counter pressure to gravity that will stop the gas cloud from further shrinking. The gas cloud becomes a stable star. This is the present state of our Sun. A molecular cloud is a cloud from which stars form. They're called molecular clouds because their hydrogen atoms form hydrogen molecules due to low temperatures....

.... hydrogen) decreases more slowly with altitude then the pressure of heavy-weight gases (e.g. oxygen). Task 2 This task can be solved using Archimedes' principle. Let us make schematic illustration for a helium balloon and all the forces applied to it: Here, and are weights of a balloon and helium inside it, is the net force of buoyancy (for both balloon and helium inside). In accordance with Archimedes' principle, or the law of upthrust, a balloon is buoyed up by a force equal to the weight of the displaced air. A balloon is in state of rest when resulting force equals to zero, i.e. when . a) A balloon is assumed to be a sphere with a diameter of 20cm, so m. Hence, its volume is...

Controlling fusion reactions involves the use of two light nuclei, deuterium and tritium, which are isotopes of hydrogen. Fusion takes place when the nuclei obtain enough energy to overcome their mutual repulsion, they can undergo the fusion reaction shown in the following figure: Figure 1: simple Fusion Reaction Nuclear fusion reactions involve the fusion of two nuclei to generate helium and a neutron in addition to a large amount of energy. The particles form a high density and super hot ionized gas called plasma. At high temperature the electrons escape from the nuclei producing a plasma of positive ions....

...with their own properties, and because the temperature decreases with height. It flies like a bird. b) The volume of a sphere is 4/3 r3 with r the radius of the sphere. In this case the diameter of the sphere is 20 cm = 0.20 m, and the radius is half of that. So the volume of the sphere is 4/3 * (1/2*0.2)3 = 4.2 * 10-3 m3 = 4.2 litres. c) The ideal gas law states that p*V = n*R*T so that n/V = p / R*T. n (number of moles) can be written as m/Mw with m = mass and Mw = molar weight V (volume) can be written as m/d with m = mass and d = density So that gives (m/Mw) / (m/d) = p / R*T or d/ Mw = p / R*T This gives for the density of Helium in the balloon d = p*Mw / R*T = 1.01325*105 * 4 / 8.314 * 298 = 164 g/m3 = 0.164...

According to Carl Segan Why we are Star Stuff
...Why we are "Star Stuff" The origin of life on earth and the origin of our universe are still a controversial because of our limited knowledgeabout it. But we know that Hydrogen and Helium are the two major components of stars. In fact the conversion of hydrogen into helium or nuclear fusion is the major reason for the immense energy produced by stars in the form of heat and light. Science has proved that the major ingredients in our body are also made of hydrogen and helium which forced Carl Segan to say that we are star stuffs. Bing Bang theory is generally accepted as the major theory which describes how our universe is evolved. It is an effort to explain what happened at the very...

Pv system 2
...Sur PV system 2 Solar energy falls among the key renewable sources of energy. The power of the sun originates from Hydrogen fusion that results to Helium, gamma rays, energy and both neutrinos, deuterons and positrons. There are other mechanisms through which Hydrogen may be converted to Helium. Helium is a stable gas formed from Hydrogen fusion, such as the nuclear reactions that occur in the sun (Gratzel 6846). The spectral peak of solar energy is at the visible region of its spectrum that is between the ultra-violet rays and infrared light. This is with an intensity of 1.375 kW/m2, also known as the solar constant (Hedegus and Luque 79). Semi conductors are used in photovoltaic cells to provide voltage as a result of light... . The...

...= buoyancy force, g = gravitational acceleration, and m = mass. On the other hand, Avogadro’s laws allows for the determination of a gas’ volume at a given density. Equation for Avogadro’s law is; molar mass/densitySTP = 22.415L/mole. By determining the volume and mass of any gas, it becomes easy to deduce a gas’ molar mass (Peck 68). This experiment involved determining the molar masses of hydrogen and helium; gases that are less dense than air. Experimental Procedures Prior to commencement of the experiment, appropriate safety requirements were performed. First, use of safety goggles and lab coats was prioritized. Secondly, water spilled on the floor was wiped in order to prevent slippage of students during the...
