The water used to slake the quicklime is a liquid, and it may be ice-cold water, but to form hydrate of lime it must assume a solid form, and hence can and does dispense with its heat of liquefaction in the change of state. You all know how hot lime becomes on slaking with water. Of course we have heat of chemical combination here as well as evolution of latent heat.
Until this should be done, the final problem of the liquefaction of hydrogen could not be regarded as satisfactorily solved. More than another decade was required to make this final step in the completion, of Faraday's work. And, oddly enough, yet very fittingly, it was reserved for Faraday's successor in the chair at the Royal Institution to effect this culmination.
In a cold abscess, such as that which results from tuberculous disease of the vertebræ, the clinical appearances are those of a soft, fluid swelling without heat, redness, pain, or fever. When toxic symptoms are present, they are usually due to a mixed infection. A tuberculous abscess results from the disintegration and liquefaction of tuberculous granulation tissue which has undergone caseation.
With similar tools, the one simply sucks the blood of its prey and the other turns every morsel of his to account, thanks to a preliminary liquefaction. And this is done with exquisite precision, though the equilibrium is sometimes anything but steady. My rearing-glasses supply me with magnificent examples.
It will be seen at once by this definition that the temperature of liquefaction of a eutectic substance is lower than the temperature of liquefaction of either or any of the constituents of the mixture. And, further, it is plain that those substances only can be eutectic which we can obtain both as liquid and solid, and hence the property of eutexia is closely connected with solution.
It will be readily seen that in the formation of a cryohydrate we have an example of eutexia, since the constituents are present in such proportion as to give to the resultant compound body a minimum temperature of liquefaction. Mag. , xvii., p. 469; F.B. Guthrie, Journ. Chem.
It is owing to the more complete knowledge of the general properties of fluids that immense progress has been made these last few years in the methods of liquefying gases. From a theoretical point of view the new processes of liquefaction can be classed in two categories. Linde's machine and those resembling it utilize, as is known, expansion without any notable production of external work.
As often as portions of these packs melt near the margin of the river, the layers of mud, sand, and gravel, which result from their liquefaction, cannot fail to assume a very abnormal arrangement very perplexing to a geologist who should undertake to interpret them without having the ice-clue in his mind. Mr.
Thanks. We can't spare the time, I reckon. So long." And me and Buck slides out the door; and that's the way the Golconda Company went into involuntary liquefaction. If you had seen me and Buck the next night you'd have had to go to a little bum hotel over near the West Side ferry landings.
Dudley looked on this fair girl, as yet innocent girl; and contrasting her with the foulness of the subject she dared discuss, it seemed to him, that a world which did not puff at her and silence, if not extinguish, was in a state of liquefaction.
