Document Summary
Mixture: physical combination of two or more pure substances. Ex: hint (does not have to be gases) Three states of matter solid, liquid, gas. Any pure substance can go through all of these states. Get nitrogen from food . other organisms can break down nitrogen (bacteria) It is absorbed into our body via the lungs and reacts with food to release energy. Usually 21% is fine in some cases can use more. Scenarios where more oxygen than 21% is used. Wounds that wont heal from radiation or diabetes. Produced from air, with an oxygen concentrator, and inhaled through a nasal tube. Atmospheric pressure decreases with altitude making it harder to breathe. Air pressure, the higher we go the less pressure there is. Fewer bits of oxygen to inhale less stuff to breathe. Ideal gas law = pv= nrt (when dealing with gas this is always true) Any argon that is inhaled in a breath is exhaled in the same amount.
