Olefiant gas, or ethylene; hence, by extension, any one of the series of unsaturated hydrocarbons of which ethylene is a type.
Both the continuous and broken curves (representing an ascent and a descent) show a fall of temperature at the adiabatic rate of unsaturated air, from about 500 metres to the highest point reached.
The temperature falls at the adiabatic rate in unsaturated air till the base of the cumulus cloud is reached.
The other, known as the Weston standard cell, in which the cadmium sulphate solution is unsaturated at all temperatures above 4°C.
The Weston standard cell, or unsaturated form is practically unaffected by changes in temperature and is the form most commonly used for laboratory work and general testing.
This is especially the case with unsaturated hydrocarbons.
The unsaturated acids, also received much attention, and he discovered the internal anhydrides of oxyacids, termed lactones.
So we find that it is the free and unsaturated fatty acids that cause butter and oil to become rank and rancid.
You may remember that the perfumes (as well as their odorous opposites) were mostly unsaturated compounds.
Obviously, then, we could make money if we could turn soft, unsaturated fats like olein into hard, saturated fats like stearin.
In the former case the solutions are unsaturated, in the latter case they are supersaturated with respect to a certain solid phase; in themselves, the solutions are stable, and are neither unsaturated nor supersaturated.
To the right of the series of curves the diagram represents unsaturated solutions; to the left, supersaturated.
The solution thereby becomes unsaturated with respect to the mixture of the active salts, and these must therefore pass into solution.
Lastly, if the temperature lies outside the transition interval, isothermal evaporation of an unsaturated solution of the composition X (Fig.
If an unsaturatedsolution of the two salts in equimolecular amounts is evaporated, potassium chloride will first be deposited, because the plane bisecting the right angle formed by the X and Y axes cuts the area for that salt.
If an unsaturated solution of the two single salts in equimolecular proportion (e.
To destroy it absolutely I need available unsaturated hydrocarbons--they'll be gases!
That the molecule of hydrogen cyanide contains a similarly unsaturated atom was demonstrated by Nef.
This deposition will make the solution unsaturated with respect to the smaller crystals and more of these will dissolve.
It is interesting to recall the fact, that the marked power of the cyanide-ion to form complexes of extraordinary stability, is also associated with a similarly unsaturated condition of the cyanide-ion (p.
The Ionizing Power of Solvents Related to theUnsaturated Condition of their Simple Molecules and to their Power of Association.
The ability of ammonia to form complex ions with simple metal ions is commonly ascribed to the unsaturated condition of ammonia (see p.
The capacity of hypochlorous acid (studied by Carius and others) for entering into combination with the unsaturated hydrocarbons is very often taken advantage of in organic chemistry.
Granting this, nothing prevents the assumption that free affinities exist in all unsaturated compounds; for example, two free affinities in NH{3}.
Unsaturated hydrocarbons, containing less hydrogen, are evidently only formed when the increase of the new molecule derived from methane proceeds from one of the other forms of substitution.
SO{3} combines with H{2}O, and also with HCl and the unsaturated hydrocarbons.
The lignone complex reacts, by its unsaturated groups, with the halogens.
Generally, the lignone is attacked under many conditions and by many reagents which are without action upon cellulose, by virtue of its unsaturated constitution, and its acid and aldehydic residues.
A compound radical, or unsaturated group, HO, consisting of one atom of hydrogen and one of oxygen.
On the other hand, ointments the bases of which contain fats of the unsaturated fatty acid series, such as oleic acid, do not satisfactorily preserve the iodine in the free state.
In the latter class it seems likely that the iodine enters into combination with the unsaturated fatty acids.
Iodine finds application in organic chemistry, forming addition products with unsaturated compounds, the combination, however, being more slow than in the case of chlorine or bromine.
The unsaturated nature of these acids renders their behaviour with various reagents entirely different from that of the preceding series.
In view of this behavior the first series is termed saturated, the second and third that of unsaturated acids.
The above solution of mercury iodo-chloride acts on both free unsaturated acids and glycerides, producing addition products.
Influence of Time--The absorption increases with the time but apparently complete absorption, so far as unsaturated bonds are concerned, occurs well within one hour's time.
When highly unsaturated fats or oils are being analyzed for moisture, an error may be introduced either by the absorption of oxygen, which is accelerated at higher temperature, or by the formation of volatile fatty acids.
Acid esters yield carbinols, many of which are unstable and readily pass over into unsaturated compounds, especially when warmed with acetic anhydride: R.
With unsaturated alkyl halides the products are only slightly soluble in ether, and two molecules of the alkyl compound are brought into the reaction.
The 'pectic' group consequently must be extended to include hydrated and soluble forms of the mixed complex of condensed and unsaturated groups with normal carbohydrates, such as constitute the fibrous lignocelluloses.
The study of these oxidations was then extended to typical unsaturated hydrocarbons--viz.

This group includes both saturated and unsaturated or condensed compounds.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "unsaturated" in a variety of sentences. We hope that you will now be able to make sentences using this word.
