13.78 kpa is.
The pressure exerted by one gas in a mixture
the amount of open space which allows a volumn or substance to move
it is a mixture of liquid rock and gasses.
Clean air is a homogeneous mixture of nitrogen, argon, oxygen, water vapor and several other gasses present in small amounts. Air that is not "clean" is air that contains dirt and dust, etc, and is a heterogeneous mixture.
Air is a mixture, even though the there is a nearly constant ratio between its two principal constituents, which are nitrogen and oxygen. To qualify as a compound, a substance must have ratios among all its elements that are as nearly constant as the precision of knowledge about atomic weights permits, and air does not qualify because it contains varying amounts of water vapor, among other variations in its minor constituents.

The total pressure of a mixture of gasses is the sum of the pressures of each gas in the mixture (Apex)
the amount of open space which allows a volumn or substance to move
Dalton's Law of Partial pressures states the total pressure of gas in a container is the sum of the individual gases. The pressure of a balloon filled solely with oxygen will deviate from the pressure in a balloon filled with a mixture of gases.
Mixture of many gasses Known Air
The partial pressure of oxygen will vary according to where you look. Atmospheric oxygen partial pressure is approximately 21% of the atmospheric pressure of the location at which you measure (typically around 1 atmosphere at sea level, making the partial pressure of oxygen at seal level 0.21 ATM or 21.3KPa). The value varies geographically and with time, but also varies in different tissues of organisms, since not all oxygen available is absorbed, and complex multicellular organisms will have certain tissues (respiring muscle) that use up oxygen, resulting in a lower partial pressure there.normal oxygen partial185.4 kPa or in another unit:100 mmHg in the arterial blood. The partial pressure on the alveolar site is about 105 mmHg.
Atmosphere. It is a mixture of gasses that surrounds the earth.
how do gasses create pressure? What are the three characteristics of gasses according to the kinetic theory
air
Yes, it's a mixture of gasses. Nitrogen and oxygen mostly but several other gasses in smaller amounts.
Let's start with understanding the question. Partial pressure is defined as the fractional percentage of the gas in the overall gas mixture times the total pressure in Atmospheres. If we assume we're scuba diving using air as our breathing gas, then the fractional percentage of nitrogen is 79% (or .79). Oxygen make up the majority of the balance at 21% (.21) Air is made up primarily of these two gasses. All other gasses that comprise air are considered "trace" gasses. Carbon dioxide is one of these trace gases, and accounts for about 0.039% percent of air by volume. If we assume for a moment that we're at sea level, then the total pressure, by definition, is 1 Atmosphere (atm). This means that the partial pressure of nitrogen in air at sea level is .79. Oxygen is .21. Carbon dioxide is .00039. Every 33 feet a diver descends in sea water adds one additional Atmosphere to the Total Pressure. This means that Total Pressure at 33 feet is 2atm and at 66 feet is 3atm. PPO2 (partial pressure of oxygen) at 33 feet is .42. PPN (nitrogen) is 1.58. PPCO2 (carbon dioxide) is .00078. At 66 feet of sea water PPCO2 is .00117 (.00039 X 3atm).
