Word Finder - ozone

definition

An allotrope of oxygen (symbol O₃) having three atoms in the molecule instead of the usual two; it is a blue gas, generated from oxygen by electrical discharge.

definition

Fresh air, especially that breathed at the seaside and smelling of seaweed.

definition

To treat with ozone.

Ozone at once attacks rubber, rapidly destroying it.

An early step accomplished by Ostwald in this direction is to define ozone in its relation to oxygen, considering the former as differing from the latter by an excess of energy, measurable as heat of transformation, instead of defining the difference as diatomic molecules in oxygen, and triatomic in ozone.

In the divalent oxygen we meet with the modification called ozone, which, although unstable, changes but slowly into oxygen.

Ozone occurs, in an amount supposed to be associated with the development of atmospheric electricity (lightning, &c.); this amount varies with the seasons, being a maximum in spring, and decreasing through summer and autumn to a minimum in winter.

Chromic acid oxidizes it to acetic acid and ozone oxidizes it to ethyl peroxide.

If ozone is passed into a solution of rubber in chloroform the caoutchouc combines with a molecule of ozone forming a compound of the empirical composition C 5 H 8 O 8.

The Siemens and Halske ozonizer, in form somewhat resembling the old laboratory instrument, is largely used in Germany; working with an alternating current transformed up to 650o volts, it has been found to give 280 grains or more of ozone per e.

Now, in this case, the first definition expresses much better the whole chemical behaviour of ozone, which is that of "energetic" oxygen, while the second only includes the fact of higher vapour-density; but in applying the first definition to organic compounds and calling isobutylene "butylene with somewhat more energy" hardly anything is indicated, and all the advantages of the atomic conception - the possibility of exactly predicting how many isomers a given formula includes and how you may get them - are lost.

The Curies showed that oxygen was convertible into ozone, and Sudborough that yellow phosphorus gave the red modification when submitted to their influence.

It is found, more especially in the case of organic compounds, that if a substance which oxidizes readily at ordinary temperature be mixed with another which is not capable of such oxidation, then both are oxidized simultaneously, the amount of oxygen used being shared equally between them; or in some cases when the substance is spontaneously oxidized an equivalent amount of oxygen is converted into ozone or hydrogen peroxide.

The ozone so prepared has numerous uses, as, for example, in bleaching oils, waxes, fabrics, &c., sterilizing drinking-water, maturing wines, cleansing foul beer-casks, oxidizing oil, and in the manufacture of vanillin.

Hydrogen dioxide occurs in a manner closely resembling ozone.

Numerous other methods of purification, some based on the oxidizing action of ozone, have been suggested.

There, the chlorine released by CFCs destroys the ozone at the rate of 100,000 molecules of ozone per chlorine released by CFCs destroys the ozone at the rate of 100,000 molecules of ozone per chlorine atom.

In the southern spring, ozone is destroyed above Antarctica, mainly by manufactured compounds called chlorofluorocarbons (CFCs ).

It is now generally accepted that the loss of stratospheric ozone is caused by chemical reactions initiated by chlorofluorocarbons.

Ozone is formed from the reaction of volatile organic compounds with sunshine.

However, 50% reductions in North America or Asia will produce a larger impact in mean ozone concentrations.

Ozone may also be negatively correlated with nitrogen dioxide in urban areas.

All showed a similar response, indicating that tolerance to ozone may not be an option in breeding improved cultivars.

This caused the region of total ozone depletion to grow upwards, with considerable partial depletion of ozone at heights up to 23 km.

The focus was to understand the role these species might play in stratospheric ozone depletion.

In the latter case, chemical ozone depletion in the Arctic would be expected to diminish.

Among the latter is chlorine monoxide, which initiates ozone destruction in the presence of sunlight.

Any excess ozone not absorbed into the water is destroyed by a machine called a destructor.

This, they claim, is evident in everything from discourses of genetic essentialism to the realities of ozone layer thinning.

Also, many problems with Chlorine containing solvents have been found (specifically the ozone layer) which makes this process somewhat less favorable.

Poisoning gases like ozone are also destroyed along with all allergens such as pollen, dust mite feces and pet dander.

All the ozone generators feature a rheostat control for adjustable ozone production.

Ozone is a lung irritant emitted from many air cleaners in the market that can trigger allergy reactions, even in small amounts.

The Ozone Instinct is the new inflatable kite from the Ozone stable of kites.

In this study, observations of ozone laminae made in Feb. 1995 during the SESAME campaign were modeling using the contour advection technique.

Participants were then exposed to 0.4 parts per million of ozone for two hours and underwent a second bronchoalveolar lavage.

The ozone layer has been torn apart & the polar ice caps are melting.

If ozone concentrations exceed 180 micrograms per cubic meter, they must inform the public and provide health advice.

And although biodiesel is cleaner than diesel, ethanol is not; it generates mutagens and carcinogens and increases ozone levels in the atmosphere.

Ozone is a gas that prevents much noxious UV radiation from reaching the Earth's surface.

Rather like the ozone octane in this respect, it needs to be " under-steered " and demands a sensitive pilot.

The aim will be to assess the radical chemistry and rates of formation of ozone and other oxidants using the modified MCM.

If aging pop star, Cher was cremated, would her plastic implants deplete the ozone?

Filters that are in working order catch paper dust and destroy ozone.

However, pollutants which lead to the formation of ozone emitted from other countries influence ozone emitted from other countries influence ozone levels in the UK.

Using natural ozone to neutralize odors The Initial Air Pure system generates ozone which occurs naturally in the environment and contains powerful sterilizing properties.

Estimates for damage costs from volatile organic carbons do not always obviously include estimates for creation of tropospheric ozone.

An accurate way of measuring atmospheric ozone is by using an Ozone Monitor.

During 1998, the park's worst recorded year for ground-level ozone, studies found damage to 30 plant species in the area.

The main cause of these is vehicle exhaust fumes reacting with sunlight to form ground level ozone.

The figure below shows a comparison of ground-based observations of column ozone above Tenerife with calculations from our 3-D model.

A few years and everyone will forget car pollution, nuclear waste and the depleting ozone layer, they claimed.
