Because Mars» atmospheric pressure at ground level is comparable to that of Earth's atmosphere at 100,000 feet — a mere 1.4 percent of Earth's air pressure at sea level — an aircraft that can fly in such conditions will help engineers learn how to design aircraft to roam Martian skies.

That unusually warm air can contribute to a «bulge» effect to the atmospheric pressure controlling how cold air flows, according to Overland, who works at NOAA's Pacific Marine Environmental Laboratory.

As it dove through the gap, Cassini came within about 1,900 miles (3,000 kilometers) of Saturn's cloud tops (where the air pressure is 1 bar — comparable to the atmospheric pressure of Earth at sea level) and within about 200 miles (300 kilometers) of the innermost visible edge of the rings.

For example, one 1965 study by researchers at the Brooks Air Force Base in Texas showed that dogs exposed to near vacuum — one three - hundred - eightieth of atmospheric pressure at sea level — for up to 90 seconds always survived.

«At normal atmospheric pressure and temperature, where air is 21 percent O2, the material already contains oxygen and can not absorb more,» McKenzie explains.

Their findings have been recently published in EPJ D and are particularly relevant for the development of novel applications in medicine, health care and materials processing because they involve air at normal atmospheric pressure, which would make it cheaper than applications in inert gases or nitrogen.

Cells were maintained in a humidified incubator at 37 °C at an atmospheric pressure of 5 % (v / v) CO2 / air.

: CO2 when it's evaporated is in your air; but CO2 can actually become a liquid, if it's at a constant temperature at a constant atmospheric pressure.

Dr. Eric Zielinski: CO2 when it's evaporated is in your air; but CO2 can actually become a liquid, if it's at a constant temperature at a constant atmospheric pressure.

VVL allows you to keep the air pressure in the intake manifold, at atmospheric or very near it, since the throttle plate, the source of regulating engine power via flow restriction, «vacuum» is eliminated.

Hyperbaric Oxygen Therapy, or HBOT, works by providing 100 % oxygen (nearly 5x that available in room air,) at approximately twice the atmospheric pressure.

If you look at the total cross section of all the air molecules in a volume 1 Meters high by 1 M ^ 2 cross section, You get figure of.0.25 * 10 ^ 26 molecules / M ^ 3 for the number of molecules at atmospheric pressure.

There is a temperature gradient caused by atmospheric radiations — warm air rises, expands and cools in lower pressure at height — but this is just the lapse rate and doesn't create cooler temps at height.

Measurement of CO2 concentration is always problematic; the «Standard Dry Air» SDA basis of measurement and comparison is at standard temperature and pressure which is a non-existent parameter; and as we are seeing, CO2 is not a well - mixed gas at all and will be defined by, amongst other variables, SH, or absolute humidity; SH can vary from 0 to 5 % by volume of atmosphere; as the SH increases, the absolute amount of other gases, including CO2, decreases; to say therefore that atmospheric concentrations of CO2 have remained stable and not been above 280ppm over the last 650my is fanciful; even if you assume past CO2 levels have not got above 280ppm the range of variation within that limit has been greater than the current increase;

Warm water on Mars, boils - it's lacks atmospheric pressure lowers the boiling point to somewhere around 5 to 10 C. And 5 C water would not boil on Mars, but it would evaporate quicker on Mars then it does on Earth - because no where on Earth is drier than Mars [due to changing temperatures, frost does form on the Mars surface at equator and at nite - this requires the thin Mars air to become saturated - but generally very dry.

In hydrostatic equilibrium, air pressure at any height is equal to the weight of air in the atmospheric column above that height.
