Helium

Dr. Hinderberg Dr. Eckeners dream of a regularly scheduled Zeppelin airship service across the North Atlantic to America was finally realized with the construction of the Hindenburg. It was designed to carry 50 passengers in a luxury and comfort never before seen in Airship Travel. It was to be one of Nazi Germany's finest airships. The Hindenburg was supposed to represent the greatness of Germany and its leader, Adolf Hitler. Because of this the Hindenburg was emblazoned with large swastikas on…

magnetic field strength and velocity. By using a Daedalon (e/m) Apparatus paired with Helmholtz coils and a glass bulb filled with helium gas, students were able to observe electrons travelling in a circular path. This is due to the uniform magnetic field produced by the coils which is perpendicular to the velocity of the electrons, the force acting on the electrons, and the helium gas that allowed students to see the electron beam travelling in a circular path. Anyways, students…

Originating from cosmic events such as supernovas, chemical elements are the foundation of all life. Billions of years ago, a violent explosion known as the Big Bang produced helium, hydrogen, and all of the matter and energy in the universe. Generated in the cores of stars, nuclei combined to form atoms which constitute the basic unit of all chemical elements. The extensive expansion of the universe induced the birth and demise of more stars and consequently the creation of more elements.…

When a star is born it can take one of two paths. It can either take the path of a high mass star or the path of a low mass star. A high mass star will be between 10-50 solar mass and a low mass star will be between .8-10 solar masses. One solar mass is equal to M⊙ = (1.989±0.004) x 1030 kg, which is A LOT. Either path it takes, the one of a high mass or low mass star it will live about 90% of it’s lifetime in its main sequence. Once achieving nuclear fusion the star slowly contracts over…

it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less than 2% of other metals. From satellite images of the sun in space, it appears to be a great, red, fiery ball of energy. The reason why it appears to be so bright is because its intense power and…

between the types there are similarities. The terrestrial planets have rocky surfaces and are similar in size, density, and radius. They also all have a similar core that is made out of mostly iron. The Jovian planets are composed of mostly hydrogen and helium. They also all have some type of water, usually as water vapor. When it comes to magnetic fields, all of the planets have one except for Venus and Mars. They do have some type of magnetic force, but they are not the same as they are for…

Who has not looked up at the night sky and admired the stars? For many years, we have used stars as a guideline for western civilization. Every night we are surrounded by billions of them. Many of us take stars for granted not knowing when we look up at the stars, there are many being born, in their mid life, and some that are dying. To get started, we have to ask what a star is. A star is massive, luminous ball of plasma held together by gravity. The nearest star to Earth is the Sun, which is…

element with the highest boiling point is Tungsten at 3143 Celsius, and the element with the lowest freezing point is Helium at -268.93 Celsius. They can look different from each other, and one could see this by looking all around them. Most of the elements that you see occur naturally, but some are manmade. Polonium and plutonium are examples of manmade elements. Elements like carbon, helium and nitrogen are one the most common in nature. All matter is theorized to come from the Big Bang,…

particles have 2 protons and 2 neutrons which are in a helium nucleus. As the alpha particles emit the helium nucleus the nucleus gives away the two protons and two neutrons. As a result of this the mass number will reduce by 4 and the atomic number will result in reducing by 2. This is known as alpha decay. One source of alpha radiation could be plutonium 239. The alpha particles have many characteristics. First of all the alpha radiation has a helium nucleus. Also the penetrating power of…

produces its energy through a process known as nuclear fusion. Nuclear fusion is when two atoms combine to form a single atom and a high amount of energy is released. In the Sun, fusion happens with mostly hydrogen atoms, which combine to form a helium atom. Two helium atoms can later combine through fusion and create a carbon atom. Like stated before, this process happens only in the core of the sun. Every second, the sun burns around 600 million tons of hydrogen atoms to keep it going. Because…
