Liquid oxygen is a mobile transparent-liquid, possessing a faint blue colour.
The temperatures employed were the boiling-points of hydrogen, oxygen and carbon dioxide.
Sulphur, iron and other substances can be made to burn under the surface of liquid oxygen if the combustion is properly established before the sample is immersed, and the same is true of a fragment of diamond.
The stop-cock being closed, the flask is now taken out of the liquid oxygen and left in the balance-room until its temperature is equalized.
Seeing that the boiling-points of nitrogen and oxygen are different, it might be expected that on the liquefaction of atmospheric air the two elements would appear as two separate liquids.
With Professor Curie he used both the liquid oxygen and the liquid hydrogen calorimeter for preliminary measurements of the rate at which radium bromide gives out energy at low temperatures.
But a use to which liquid air machines have already been put to a large extent is for obtaining oxygen from the atmosphere.
This substance is composed of hydrogen andoxygen in the proportion of two to one; that is, to each atom of oxygen there will be found two atoms of hydrogen.
When the nitrogenous substances are oxidized, the used-up oxygen products are eliminated by the kidneys in the form of urea and more or less highly oxidized substances, such as ammonia and other salts, purin bases, and creatinin.
This foodstuff, while composed of the same chemical elements that go to make up the carbohydrates, contains these elements in different proportions; that is, fats contain less oxygen and more hydrogen than carbohydrates.
In a ten-stone-ten man the weight of oxygen is no less than 106 lbs.
With calcium and oxygen it forms the exceedingly hard phosphate of calcium that gives the bones their rigidity.
And this dissociation is nothing more than if you took some white of egg and mixed with it a quantity of oxygen so as to form urea, carbonic acid, and water.
Sodium, potassium, and ammonium are mixed with hydrogen and oxygen to make it--the pungent ammonia, as well as the soda and potash which are the cleansing principles of soap.
In choosing stock for the aquarium it should be remembered that a sufficient quantity of vegetable life is required to furnish oxygen for the fish.
Gases are not very abundant in water, as it only holds in solution a limited quantity of oxygen and carbonic acid.
Both of these the plant needs, though in varying quantities: the carbon to build up its starch, and the oxygen to use up in its growth.
He was going to the intake of the city's ventilation plant, and no unmasked creature dependent for life upon oxygen could bar his path.
Its atmosphere, while rich enough in oxygen and not really poisonous, was so rank with indescribably fetid vapors as to be scarcely breatheable.
The chemical constitution of this gazeous fluid is best ascertained by burning it in a vessel of oxygen gas, over lime-water in a pneumatic reservoir, by means of a bladder and bent brass pipe.
The electrical circuit of the body is the circulating blood, and when the oxygen and the nitrogen are taken in through the lungs the electro-negative ions go in one direction.
There is a great "Chemist-Physicist" superintending nature's operations, sorting out two parts of hydrogen and one of oxygen to compose the raindrop and the waters of the ocean.
The oxygen of the air keeps alive the fire of physical life, and the body may be compared to a flame fed unceasingly by electric fire from the sun and atmosphere, according to the laws of electric combustion.
When oxygen is taken into a body it excites the elements in the same manner as the negative chlorine attacks the zinc in the battery.
The want of oxygen or this electric energy from the air extinguishes the flame of life as it extinguishes the flame of a lamp.
They form storage cells in which a current of electricity decomposes the liquid into oxygen and hydrogen and form materials which again give electricity, motion and heat.
Vegetable life, which is next above them, have organisms, and are sun engines breathing in nitrogen and giving out carbonic acid or oxygen to sustain animal life.
A want of oxygen extinguishes the flame of life as it extinguishes the flame of a lamp.
The oxygen of the air keeps alive the fire of physical life, and the body may be compared to a flame being fed unceasingly according to the laws of combustion.
Priestley's discovery ofoxygen was epoch-making, but does not represent all that he did.
Thus believing, it will not be out of place to seek some light upon the occupation of the discoverer of oxygen after he came to live among us--with our fathers.
These end in a system of capillaries in between the air cells of the lungs, where carbon dioxide is thrown off and oxygen taken on.
If for any reason the supply of oxygen is cut off from the lungs, we will have the body dying the result of asphyxia or apnea.
The blood gives off carbon dioxide to the air-cells and the air in the cells furnishes oxygen for the blood.
This function is entirely dependent upon the presence of hemoglobins, which have the power of combining easily with the oxygen gas.
The function of the red blood corpuscles is to carry oxygen from the lungs to the tissues.
The tank in which the liquefied oxygen was kept automatically gave off its gas so evenly that the air remained normal, while the lime contained in cups absorbed the carbon dioxide as fast as they exhaled it.
It would be better, therefore, to have such a sun as you describe and accompany it in a yacht or private car like this, well stocked with oxygen and provisions.
If there is any way by which the visible substance of these fungi can be converted into its invisible gases, as water into oxygen and hydrogen, what we have seen can be logically explained.
We must analyze it to see if it contains our own proportion of oxygen and nitrogen.

The only name which suggests itself is oxyzone, a combination of oxygen and ozone.
The stuff is a polymerization, or condensation, to speak roughly, of the oxygen of the air.
If the oxygen polymerizes before it enters the body, these masks ought to stop it, but if it polymerizes under the influence of heat and moisture in the lungs, they will be useless.
The oxygen takes this form which the lungs cannot assimilate except with great difficulty and with great damage to the tissues.
Prior to the second day oxygen must either have been non-existent, or it must have existed in a form and under conditions very different from those under which it exists now.
It is estimated that oxygen constitutes, by weight, nearly half of the solid crust of the earth.
Thus, when oxygen and hydrogen are combined to form water intense heat is produced.
