∙ 10y agoThe pressure exerted by one gas in a mixture
the amount of open space which allows a volumn or substance to move
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.
Air consists of a mixture of gasses, including oxygen and carbon dioxide. Wind is the movement of air. Therefore, when there is wind, these gasses move.
No, unfiltered air is a mixture of gases like nitrogen, oxygen, and carbon dioxide, as well as particulate matter like dust and pollen. These components are not uniformly distributed throughout the air, making it a heterogeneous mixture.

Dalton's law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas in the mixture. Each gas in a mixture exerts a pressure that is independent of the other gases present.
One common example of Dalton's Law of Partial Pressures is in scuba diving, where the total pressure underwater is a combination of the partial pressures of gases like oxygen and nitrogen in the air mixture breathed by divers. Another example is in the use of oxygen masks on airplanes, where oxygen is provided at a higher partial pressure to compensate for the lower atmospheric pressure at high altitudes.
Mixture of many gasses Known Air
The partial pressure of oxygen in a balloon depends on the total pressure inside the balloon and the percentage of oxygen in the air mixture. For example, if the total pressure is 1 atm and the air mixture contains 21% oxygen, then the partial pressure of oxygen would be 0.21 atm.
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).
