Lighter‚ basic and abundant elements like hydrogen and helium were formed during the Big Bang. During Big Bang‚ space expansion cooled the early energy dominated universe and a lot of energy transformed into matter. These basic elements were then able to create the early stars and also the stars of today. Inside of these stars lighter elements fused to release large quantities of energy and in the process of doing that converted hydrogen and helium into heavier elementary particles. Such elements would

William Ramsay William Ramsay was born on the second of October‚ in the year 1852. William‚ and his parents‚ William and Catherine‚ lived in Glasgow‚ Scotland. William Ramsay performed his work in his native town‚ until 1870 when he went to Tübingen and earned his doctorate in 1872. When returned to Scotland later that year‚ he became an assistant chemist at the Anderson College in Glasgow. Eight years later‚ he was appointed principal and professor of chemistry at London University‚ which

father‚ sister and his lover Cal‚ let a white helium filled balloon go into the air. The white helium balloon symbolizes Andre’s departure and represents his spirit rising to heaven. “They represent the soul. When you let it go‚ it means you’re letting his soul ascend to heaving” (Cal page 737). Cal‚ the main character and Andre’s mother have the toughest time letting go of the helium balloons while Penny (his sister) and Andre’s Father let go of the balloons with no problem. Andres’ mother never knew

Nuclear fission is a atomic reaction that happens in the core of stars‚ mostly converting hydrogen to helium‚ but it requires a lot of energy. Nuclear burning is

ascent – and safe descent – in modern times took place by hot-air balloon in the 18th century. Each of the two World Wars led to great technical advances. Consequently the history of aircraft can be divided into five eras: Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies‚ filled with a relatively low-density gas such as helium‚ hydrogen‚ or hot air‚ which is less dense than the surrounding

Fifteen to twenty billion years ago‚ the universe arose as a cataclysmic eruption of hot‚ energy-rich sub-atomic particles. Within seconds‚ the simplest elements (hydrogen and helium) were formed. As the universe expanded and cooled‚ material condensed under the in-fluence of gravity to form stars. Some stars became enormous and then exploded as supernovae‚ releasing the energy needed to fuse simpler atomic nuclei into the more complex elements. Thus were produced‚ over bil-lions of years‚

though it’s very common element in the universe. In the earth’s atmosphere‚ neon only comprises 0.0018 percent of the volume. On the earth‚ neon is always present as a gas. Neon has three stable isotopes‚ and it’s the second lightest noble gas‚ after helium. Two different types of neon are commonly used in the world. Neon glow lamps are tiny; they have been used as power on indicators. Neon is not a very common element‚ but the places it is most abundant is in the earth’s atmosphere‚ and trapped with

Dana Leamaster February 13‚ 2013 Informative Speech: The Big Bang Theory How did the universe begin? How did matter come to exist? We all know that the universe exists‚ however‚ this knowledge alone has not satisfied mankind’s quest for further knowledge and understanding. Much time has been spent looking for some clues. Most of what we know is still only a speculation. The three topics I’d like to discuss are what exactly the Big Bang theory is‚ the first atoms‚ and the age of
