The word 'voc' is a shortened form of the Portuguese word voce. The Portuguese pronunciation is as follows: voh-SAY. The second syllable is pronounced the same way as the letter 'c' in Portuguese. And so Portuguese speakers who text message, or have a limited amount of space in which to fit a message, may resort to 'voc' as an understandable abbreviation.

What do you mean by solubility of VOCs?
Solubility is the aptitude of a chemical substance to be soluble (to form a homogeneous solution) in a given solvent. I suppose that you think to volatile organic compounds.
What is the most common name for ground level ozone pollution?
fog,smog,smoke,VOCs
What is the name of two air pollutants that form ozone?
Oxides of nitrogen (NOx) and volatile organic carbons (VOCs).
Is Plywood natural?
The wood chips themselves are natural, but the VOCs in the adhesives/resin used to bond the chips together can be harmful.
Is formed in the atmosphere when chemicals called volatile organic compounds VOCs and nitrogen dioxide NO2 are acted upon by sunlight?
ozone
How do VOCs contribute to troposphereic ozone?
Volatile Organic Compounds are decomposed compounds. They burn to emit CO2 with could form ozone.
Why organic solvents are no longer used?
What gave you that idea? They have many industrial uses. Also dry cleaners use them. But in all these uses there are regulations requiring solvent recovery systems to prevent their release to the environment and allow their recycling and reuse. Maybe you are thinking of the replacement of VOCs in paint with other chemicals. VOCs contribute to air pollution, some can create smog.
How does one detect VOC's?
VOCs are detected for two purposes. The first is to determine if an area is safe from explosive or combustible levels of gas, and the second to quantify concentrations of specific VOCs due to their toxicity or as compliance with environmental guidelines.Combustible and exposive mixtures are measured with an explosimeter. A device which operates on the principle of resistance proportional to heat -- a wire is heated, and a sample of the gas is introduced to the hot wire. Combustible gases burn in the presence of the hot wire, thus increasing the resistance and disturbing a Wheatstone bridge. The Output is interpreted as a concentration of gas.Detecting VOCs for speciation is done by:* Bagging a sample for later analysis at a laboratory with a GC/Mass Spec unit * Absorbing VOCs from the gas stream on activated carbon for later desorbtion and laboratory examination * In situ analysis with a portable GC/Mass Spec. * By passing a laser beam through the gas and noting reflection or adsorption bands
Which is source of emission leading to the eventual formation of surface ozone as a pollutant?
The primary source of emission leading to the formation of surface ozone as a pollutant is the release of nitrogen oxides (NOx) and volatile organic compounds (VOCs) from human activities, such as fossil fuel combustion, industrial processes, and vehicle emissions. These emissions react with sunlight to form ozone, particularly in areas with high levels of NOx and VOCs.
What can the abbreviation VOC be short for?
VOC stands for volatile organic compound. VOCs are organic chemicals that have a higher than usual vapour pressure which makes them dangerous to the environment.
What is the composition of London smog?
Photochemical smog is composed of many different compounds, but the three major ones are ozone, PAN and VOCs (Volatile Organic Compounds).Ozone is written as O3 and is the product of the following reaction:O+O2--->O3.The singular O is formed when NO2 decomposes because of sunlightPAN(peroxyacetylnitrate)is the product of VOCs oxygen and nitrogen oxide.VOCs are uncombusted fuels, often the product of engines.
Is smog good for plants?
There are two types of smog, the good old smoke and fog type and photochemical smog ( a mixture of ozone, VOCs, PAHs and other nasties) For both types the answer is no.
