Ozone Danielle Farrar March 16‚ 1997 Triatomic oxygen‚ O3‚ is most commonly known as ozone. It has a resonance structure‚ and can be drawn in two different ways: O=O- O-O=O It is a bluish‚ explosive gas at room temperature‚ and has a boiling point of -119°C. It has a melting point of -193°C‚ and is a blue liquid. It ’s critical temperature and pressure are -12.1°C and 53.8 atm‚ respectively. It has a pleasant odor in concentrations of less than 2 ppm‚ and is irritating and injurious

radiation. Way up in the part of the atmosphere‚ called the stratosphere‚ a layer of gas filters out most of the sun’s damaging ultraviolet rays. This layer of gas is called ozone and is located about five miles to 25 miles above the surface of the Earth. (Bright‚ 1991). Only about one-millionth of our atmosphere is made up of ozone. But it has a tremendously important job. Ozonecan absorb‚ or soak up‚ the part of sunlight called ultraviolet radiation. Some ultraviolet radiation still gets through

OZONE LAYER The Earth ’s ozone layer protects all life from the sun ’s harmful radiation‚ but human activities have damaged this shield. Less protection from ultraviolet light will‚ over time‚ lead to higher skin cancer and cataract rates and crop damage. The ozone layer is one layer of the stratosphere‚ the second layer of the Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. Ozone is only a trace gas in the atmosphere only about 3 molecules for every

The Ozone Layer: What does it do and what happens when it is depleted? The ozone layer is one of the most debated scientific subjects of the last decade. The growing problem of its depletion is being researched heavily all over the world‚ and methods are being researched to try and solve the problem. There have also been many debates concerning the relationship between the ozone layer and the onset of global warming. Before solutions can be developed‚ however‚ what the ozone layer actually does

Ozone‚ pronounced OH-Zohn‚ is a form of oxygen that is present in the earth’s atmosphere in small amounts. Ozone in the upper atmosphere is a major factor in making life on earth possible. But ozone in the lower atmosphere contributes to air pollution. Society has been widely addressed with the many problems that we are having in our environment today. A major problem is that of CFCs. CFC stands for Chlorofluorocarbons which are found in many of the aerosol spray cans. In December of

The ozone layer is a deep layer in the stratosphere‚ encircling the Earth‚ that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates

Ozone Our Global Sunscreen By Mike Carlowicz t’s not often that scientists get to conduct experiments that seem like they come out of a science fiction novel or a video game. Yet‚ that is what some researchers at NASA did a few years ago. Atmospheric physicists Paul Newman and Luke Oman built a simulation of the Earth’s atmosphere and then proceeded to strip away our protective ozone layer. Their computer model reproduced the chemistry and circulation of the air; natural variations in temperatures

Effect of CCl3F on Canada’s Ozone Layer Data Analysis and Interpretation 1. It took 25 yrs for CCl3F to enter the stratosphere (1930 to 1955). 2. The ozone layer above Canada began to decline in 1975. 3. Once the production of CCl3F was drastically reduced‚ it took 20 years for the CCl3F levels to decrease in the stratosphere. Conclude and Communicate 4. CFCs (Chlorofluorocarbons) are inorganic man-made chemicals that have been in production for more than 50 years in Canada. They were

Hole in the Ozone is a documentary film that educates its audience the relationship of ozone and chlorofluorocarbons (CFCs) and its effects to our atmosphere. Hole in the Ozone also known as Ozone Depletion or Ozone Thinning had been an issue since the 70s and 80s. Even until now‚ this has become one of our major environmental issues. It is surprising to know that the ozone performs a major part in protecting us from dangerous radiation that the sun emits to our planet‚ even though it is also part

Ozone As A Disinfectant Joey Finnegan Section 01 October 3‚ 2010 Ozone is a highly reactive gas composed of three oxygen atoms. Ozone is an unstable gas that can destroy bacteria and viruses. Ozone can have many different effects on humans depending on where it is in the atmosphere‚. Some of these effects can be harmful although some can be good. An excess‚ or high concentration of ozone in an inclosed area can be quite harmful to humans although in moderation and if used properly ozone
