The process of extracting moisture (as by heat)

Usage examples of evaporation.

When the tentacles do not begin moving for a much longer time, namely, from half an hour to three or four hours, the particles have been slowly brought into contact with the glands, either by the secretion being absorbed by the particles or by its gradual spreading over them, together with its consequent quicker evaporation.

Absolute alcohol will then dissolve out the alkaloid, and leave it on evaporation in a crystalline form.

Taking some azotic acid, he mixed it with glycerine, which had been previously concentrated by evaporation, subjected to the water-bath, and he obtained, without even employing a refrigerant mixture, several pints of an oily yellow mixture.

This cooling process is hastened by the evaporation of the perspiration poured out at the same time, as we have seen.

The evaporation from the surface is so rapid that one can hardly appreciate the profuseness of the perspiration going on.

With waves and tides and hot rocks and solar evaporation to concentrate the amino acids and proteinoids found in the seas and to turn them into the precursors of life, with lightning and heat and radiation and ultraviolet light to turn simple molecules into more complex ones, with the physics and chemistry of the universe itself to produce the necessary elements and simple compounds in appropriate amounts, it may even be said that life on Earth was inevitable, that it had to appear as soon as a microsphere was formed with just the right bit of nucleic acid within itself.

Drosera are continually secreting viscid fluid to replace that lost by evaporation, yet they do not secrete the ferment proper for digestion when mechanically irritated, but only after absorbing certain matter, probably of a nitrogenous nature.

Of those listed above, acetonitrile is preferred since it is non-reactive and mobile at the temperature used, and is relatively volatile and hence readily separable from the reaction mixture by evaporation in vacuum.

If the dish becomes stained during evaporation, take up with a few drops of hydrochloric and sulphurous acids, evaporate, and then treat with carbonate of soda.

It was narrow and long, and bauhin ia trees had been planted along its border to deter evaporation.

But because all water which has been in contact with the earth has some dissolved mineral substances, while that which goes away by evaporation is pure water, a lake without an outlet gradually becomes so charged with these materials that it can hold no more in solution, but proceeds to lay them down in deposits of that compound substance which from its principal ingredient we name salt.

The more completely we withdraw this water from the surface, and carry it off in underground drains, the more do we reduce the amount to be removed by evaporation.

The writing made with such inks quickly dries by the evaporation of the water, when it merely requires the application of a little soap and water to wash them out, leaving the paper absolutely clean, besides being fugitive.

Gradual evaporation of moisture causes a change not only in color but in the case of the iron and gall inks, in their chemical constitution, being immediately affected by their environment, whether due to the character of the paper on which they rest, the kind or condition of the pen used, or most important of all, the elements.

With waves and tides and hot rocks and solar evaporation to concentrate the amino acids and proteinoids found in the seas and to turn them into the precursors of life, with lightning and heat and radiation and ultraviolet light to turn simple molecules into more complex ones, with the physics and chemistry of the universe itself to produce the necessary elements and simple compounds in appropriate amounts, it may even be said that life on Earth was inevitable, that it had to appear as soon as a microsphere was formed with just the right bit of nucleic acid within itself.
