Ultraviolet Radiation Ozone Layer
1,027 wordsGreenhouse Effect On a bright, cool day, most people notice the sun's rays as feeling good on their skin. By nature, many of us even try to stay on the sunny side of the street while walking. The sun is 93 million miles away from earth and its energy travels to us in moving waves called radiation. The energy becomes heat, light and other energy too. Visible sunlight allows us to see the world around us, but there is invisible sunlight, too. These rays can't be seen, but some can be felt as heat....

Speed Of Light Time Of Day
1,333 wordsOur view of the sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interac...

Life On Mars Washington D C
1,018 wordsIf life ever evolved on any of the other planets, Mars is the likeliest candidate. After Earth, Mars is the planet with the most hospitable climate in the solar system. So hospitable that it may once have inhabited primitive, bacteria-like life. Outflow channels and other geologic features provide extensive evidence that billions of years ago liquid water flowed on the surface of Mars. Continuing changes is an accomplishment in modern American technology and it gives the world a step forward in ...

Left Hand Side Atmospheric Pressure
1,199 wordsChemistry Independent Study: Gas Laws Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases...

(Siebring, Richard, Page 32) Guillaume Amontons (d. 1705) developed the air thermometer, which uses the increase in the volume of a gas with temperature rather than the volume of a liquid. The air thermometer is an excellent demonstration of Charles' law because the atmosphere maintains a fixed downward pressure above a small mercury plug of consta...

Nuclear Reaction Naked Eye
1,061 wordsSTARS A star is a large celestial body composed of gravitationally contained hot gases giving off electromagnetic radiation, especially light. The sun is actually a star. Unlike the sun the stars seem to be fixed, but in fact stars are in rapid motion, but their distances are so great no relative changes can be seen with the naked eye. The sun is a typically star, with a visible surface called a photosphere, which an atmosphere of hot gases, and above them an outlawing stream of particles called...

Amount Of Energy Oxygen Atoms
1,983 wordsPlanning In this investigation I will be burning alcohols to heat up a beaker of water. I will be burning five alcohols, methanol, ethanol, propanol, butanol and pentanol. The aim is to find out how much energy is produced when burning these alcohols. An alcohol is a series of organic homologous compounds, with the general formula Cn H n + 1 OH´ . Alcohols react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because ...

5 Billion Dollars Angular Momentum
934 wordsWhat is a hurricane? A hurricane is a tropical cyclone that has a maximum sustained wind of at least 75 mph. The primary energy source for tropical cyclones is the latent heat released when water vapor condenses. Only extremely moist air can supply the energy necessary to spawn and maintain tropical storms, and only very warm air contains enough moisture. Tropical cyclones, therefore, form only over oceans with water temperatures of at least 80 deg F. After they have formed, such storms tend to ...
