Among the atmospheric constituents that, according to this view, Mars would be unable permanently to retain is water vapor.
Experiment has shown that the temperature of the air varies with changes in the amount of carbonic acid and of water vapor that it contains.
For with the air is mixed a quantity of water vapor.
Fourth, advantage might be taken of some agency such as water or water vapor, having a high specific heat.
The full force of this upward pressure, however, is not spent in compressing the gas within the tube, for since it is collected over water it contains a certain amount of water vapor.
In this way it has been proved that 2 volumes of hydrogen and 1 volume of oxygen combine to form exactly 2 volumes of water vapor, the volumes all being measured under the same conditions of temperature and pressure.
In such cases there is present in the gas a certain amount of water vapor.
The presence of water vaporis readily shown by its condensation on cold objects as well as by the fact that a bit of calcium chloride when exposed to the air becomes moist, and may even dissolve in the water absorbed from the air.
In the case just cited, the union of two volumes of hydrogen and one of oxygen results in precisely two volumes of water vapor.
Mars has no detectable oxygen, but does contain small amounts of water vapor, more abundant carbon dioxide, possibly a large surface flux of solar ultraviolet radiation, and estimated daily temperature variations of 100 deg.
This collapse occurs because each of the gases present in the alveoli (oxygen, water vapor, and carbon dioxide) is subject to prompt and complete absorption from the alveoli by the blood.
Relative humidity At a definite temperature, the atmosphere can hold only a certain amount of water vapor.
Even snow and ice give off water vapor, though in very small quantities.
As long as the actual amount of water vapor in the air is less than that which the air can hold, no rain falls.
The air thereby cooled has a lower capacity for the retention of water vapor, a function of its temperature; the colder the air the less water vapor it can take up.
He added: "The spectroscope has plainly shown that there's water vaporin what little air there is.
It prompted the geologist to say: "Kinney--if that reflection is really due to ice, then there must be plenty of water vapor in the air.
For this reason coals containing high percentages of volatile matter will produce a larger quantity of water vapor, and thus increase the apparent percentage of nitrogen.
Saturated steam is water vapor in the condition in which it is generated from water with which it is in contact.
The effect must be greater, however, than would appear from the figures given above, for any change in temperature has an effect on the amount of water vapor, which in turn causes further changes of temperature.
This fact, plus the effect of water vapor, would seem to indicate that a doubling or halving of the amount of CO{2}, would have an effect of more than 1.
Another result is a diminution of water vapor, not only because cold air cannot hold much vapor, but also because the oceanic area from which evaporation takes place is reduced by the emergence of the continents.
Possibly the sun's electrons and its electrical waves produce indirect effects by being converted into heat, or by causing the formation of ozone and the condensation of water vapor in the upper air.
Professor Lowell, despite the aid the admission of water vapor in Mars would give to his position, also doubts whether the spectroscope is able to detect the evidence through our own moisture-laden atmosphere.
Water vapor, no spectroscopic proof of, Campbell, 135.
They must not be mistaken for parasites, as they have roots of their own through which they absorb nourishment, mostly as water vapor, but also as liquid water held in the bark and refuse in which they grow.
With carbon dioxide going in, oxygen, water vapor and, as we have seen, even liquid water coming out of the stoma of leaves, it might be surmised that these busy little pores and their guard cells had done work enough for the plant.
Sometimes, around the edges of the leaves of the common garden nasturtium, drops of water may be found, literally forced out as drops, rather than transpired as water vapor.
As this dries up under the heat of the day, or if there occurs one of the torrential downpours to which such regions are frequently subjected, there rises from the forest in plainly visible waves a vast quantity of water vapor.
It's never the same any two days in succession, because the air can hold more water vapor when it is warm than when it is cold.
In the layers of the atmosphere, one or two miles high, where the air is not as cold and where the content of water vapor is higher, the flakes have more opportunity to grow as they slowly sink through the air.
When the air is full of water vapor, it hasn't the same readiness to absorb it.
Not only that, but colors of the sunset vary as the particles of dust which reflect the rays of light, are enveloped by water vapor.
Water vapor will, therefore, go before nitrogen, oxygen or carbonic acid gas.
This gas constitutes of itself an atmosphere; while another phenomenon, to wit, their blue girdles as they melt, affirming their substance to be snow and ice, enables us to precise the fact that this gas is water vapor.
Water vapor is a great upsetter of atmospheric equilibrium and commotion in the air the spoiler of definition.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "water vapor" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
