It was that for every gas there is a temperature above which it is impossible to liquefy it by pressure.
Hold it with the pincers, glowing as it is, before it has become cold, and strike it with a large hammer strongly over the anvil, and if it be broken or split you must liquefy it anew as before.
Our miners call them fluores, not inappropriately to my mind, for by the heat of fire, like ice in the sun, theyliquefy and flow away.
Hold it with pincers, glowing as it is, before it has become cold, and strike it with a large hammer strongly over the anvil, and if it be broken or split you must liquefy it anew as before.
The cooling effect of passing a gas such as air or oxygen through a narrow orifice has been used to liquefy the gas.
It is possible thus to liquefy hydrogen, which shows that at the low temperature at which the process is usually started (an initial cooling is applied) the passage through the orifice has a cooling effect as in the other cases.
The answer to this question, furnished about half a century ago through the researches of Thomas Andrews, is that no amount of pressure will liquefy a gas unless its temperature is below a certain point.
Fahrenheit) before it will liquefy under any pressure, and the critical temperature of nitrogen is still lower.
Efforts to liquefy the gases of the atmosphere were unsuccessful for a long time on account of the difficulty of attaining such low temperatures.
It will be seen that by the use of liquid or solid hydrogen as a cooling agent, it should be possible to liquefy a body having a critical temperature of about 6 deg.
Given a sufficiently low temperature, therefore, it is the easiest gas to liquefy so far as pressure is concerned.
The whites must be stirred in with greatest gentleness,—any quick stirring will cause them to liquefy and spoil your soufflé; when the whites are blended, bake in a buttered dish twenty minutes.
It does notliquefy gelatine, and remains strictly localised to the track of the inoculating needle.
We have already seen that these bacilli do not as a rule liquefy gelatine, form spores, are non-motile, and are easily killed by heat.
Saline compounds are the substances most frequently employed for this purpose, and those which have the greatest affinity for water, and thus liquefy the most rapidly, produce the greatest degree of cold.
When the salt has become quite white, raise the heat so as to liquefy it, pour on to a clean flagstone, and when it has solidified break into fragments, and keep in a stoppered bottle.
Moreover, certain mushrooms, the coprini, liquefy spontaneously and turn into a black fluid.
The brains do not liquefy either: they simply melt into a thin gruel.
As meat is a compact substance, which does not liquefy of its own accord, there must, in that case, be a certain recipe to dissolve it into a fluid broth.
Will the worms accept these viands and, above all, can they manage to liquefy them, which is the first and foremost condition?
In every single instance I have obtained negative results, and, as far as my experiments go, helium remains a permanent gas, and apparently much more difficult toliquefy than even hydrogen.
The discovery of these properties suggested an explanation of the failure of previous attempts to liquefy air.
Cailletet, having fruitlessly subjected air and hydrogen to a pressure of one thousand atmospheres, came to the conclusion that it was impossible to liquefy those gases at the ordinary temperature by pressure alone.
By employing such low temperatures, it was possible, with the aid of pressure, to liquefy the majority of the other gases.
As a group these bacteria are characterized by their inability to liquefy gelatin or develop spores.
So far as known they are able to liquefy gelatin (also a peptonizing process) and form spores.
Profile view of gelatin plate culture; b, a liquefying form that dissolves the gelatin; c and d, surface colonies that do not liquefy the gelatin.
Most seminal liquors dilute of themselves, and liquefy when exposed to the air or a certain degree of cold; but they thicken when a moderate degree of heat is communicated to them.
That ice should liquefy at the surface of a cavity is, I think, in conformity with all we know concerning the physical nature of heat.
As has been said, it was by adopting this principle of self-intensive refrigeration that Professor Dewar was able to liquefy hydrogen.
Now after this statement, it is clear that what the low-temperature worker does when he would liquefy a gas is to become the champion of the force of cohesion.
It will often solidify at a higher temperature than that at which it stood liquid; and will liquefy at a temperature notably below that at which it became or stood solid.
Let us consider them in reference to the substance which is seen to liquefy in the vial or ampulla in the reliquary.
Liquefy the nutrient gelatine and wort gelatine tubes by immersing them in the same water-bath.
Liquefy and measure out into a sterile flask: Nutrient agar 1000 c.
Liquefy and measure out into a sterile flask: Nutrient agar 600 c.
Liquefy and measure out into a sterile flask Nutrient agar 1000 c.
Liquefy and measure out into a flask Nutrient agar 750 c.
Liquefy a tube of gelatine (or agar) by heat, pour it into a Petri dish, and allow it to solidify.
Liquefy a tube of nutrient agar (or gelatine) and pour into a Petri dish to the depth of about 4 mm.
Liquefy three tubes of nutrient agar--nutrose agar or the like.
By evaporating it under a diminished pressure, he gets much higher degrees of cold, and these have enabled him to both liquefy and solidify nitrogen and air.
The failure of preceding attempts to liquefy oxygen is due to lack of knowledge of its ‘critical point,’ and the law which that phrase describes.
By recent researches it has been found possible to liquefy gases at a very low temperature and increased pressure, with the result that now nearly all known gases as hydrogen, oxygen, and carbonic acid are to be obtained in liquid form.
Most of the elementary bodies are to be found in a gaseous form as hydrogen, oxygen, fluorine and chlorine, though it has been found possible to liquefy even these gases.
The liquid air cycle equipment would be using the cryogenic hydrogen fuel to chill and liquefy the rush of incoming air; oxygen would then be injected into the scramjets at pressures impossible to achieve in conventional engines.
Then finally the Japanese engineers had perfected the liquid-air-cycle process, permitting the cryogenic hydrogen fuel to be used to liquefy a portion of the incoming air and inject it under high pressure into the engine.
This is just what one would expect, because the heat needed to liquefy the salt must come from somewhere, and naturally it comes from the water, thereby lowering the temperature of the water.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "liquefy" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: cut; decompose; dilute; dissolve; flux; fuse; infuse; liquefy; melt; percolate; run; solve; thaw; thin
