There are three major gases in the air we breathe assuming that we are at sea level or at least not standing on top of a mountain. Nitrogen accounts for 79.01%, Carbon Dioxide accounts for 0.04% and Oxygen accounts for 20.95%. When we breathe out the balance is Nitrogen at 74.5%, Carbon Dioxide at 3.6% and Oxygen is 15.7%. Also water vapour is present at 6.2%. You can see why it is possible to give artificial respiration or mouth to mouth to a victim when our expired are contains almost 16% oxygen. This shows that we only use about 25% of the oxygen we take in at each respiration. Hope this helps.

We breathe in all gases present in the air. The two most abundant constituents of air are nitrogen and oxygen.
Most air conditioning systems contain 5 major components. These are the evaporator, compressor and condenser, and either a receiver/drier and expansion valve, or an accumulator and orifice tube.
If the air is clean, you'll breathe in oxygen. If dirty, you'll breathe in polluted air which can damage your lungs. An example of polluted air is car exhaust or second-hand smoke. . To more specifically answer the question, the air we breathe is made up of several gases. Air is mostly nitrogen (~78%), and oxygen (~21%), and the remainder is a mix of hydrogen, carbon dioxide, argon, helium, neon, particulate matter, and other gases.
The air we inhale is roughly 78% by volume nitrogen, 20% oxygen, 1% argon and 0.04% carbon dioxide, helium, water vapour, and small amounts of other gases. The gases we exhale are essentially the same except that there is an increase (roughly 4% to 5%) in carbon dioxide and 5% to 10% less oxygen than was inhaled. Low quantities of other gases and compounds like ethanol (more if alcohol has been drunk) are also exhaled.
The 5 major types of pollution are gases, noise, garbage, high-powered waste, and chemicals.
The concentration of greenhouse gases in the air, largely water vapor, carbon dioxide and methane, are causing an enhanced greenhouse effect which is global warming.The amounts of greenhouse gases in the air are:5% Water Vapor0.039% CO2Trace (less then 0.001%) small amounts of other gases (methane, nitrous oxide etc)Water vapor absorbs heat like other greenhouse gases.

Many of the activities that humans do have a direct or indirect link to contributing gases into the atmosphere. For example if you want to go swimming at a pool which is a 5 minute drive from your house, the swimming would not produce greenhouse gases into the air but the 5 minute drive would. But if you participated in a car race that would have a direct link to producing greenhouse gases becouse when you drive a normal petrol or gasoline powered car you would be producing carbon dioxide into the air.
We breathe in all gases present in the air. The two most abundant constituents of air are nitrogen and oxygen.
There are 5 parts involved in respiration:1. Pulmonary ventilation or breathing.2. External respiration where air flows into the lungs and gases exchange (O2 load/ CO2 unload) and air goes out.3. Transport of respiratory gases by way of blood transport from the lungs to body cells and back to lungs.4. Internal respiration is where exchange of gases occurs at the body capillaries (O2 unload/CO2 load).5. Cellular respiration which is the use of oxygen by cells to produce energy (production of CO2).
5 examples of gases found in the normal home environment include; oxygen (air), nitrogen (most abundant element found in the air), carbon dioxide (air and the bubbles in fizzy drinks), argon in air and finally, methane if there is a gas supply, or propane or butane in fuel gas bottles. Carbon monoxide and SO2. are present in polluted air. You might have helium in a balloon.
You would not find any gases in a cupboard other than what you would find in normal air. The gases you would find in normal are are: Nitrogen (78%) Oxygen (20%) Carbon Dioxide (0.03%) Rare Gases (Helium, Krypton, Argon, etc. 0.97%) And Water Vapour (varying amounts) These would be the five basic gases you would find in a cupboard.
Air is a well defined composition of various gases present in different proportions however, the principal components of air are: 1. Nitrogen 78 % 2. Oxygen 3. Carbon dioxide 4. Argon 5. Water vapours 6. Neon 7. Xenon 8. Krypton 9. Radon 10. Helium
Air is a mixture of gases. Not a chemical compound of them, just a mixture. Like you get when you pour some water, some whiskey, some vinegar, and maybe some milk all into a jar and stir it up. -- Air is mostly Nitrogen ... more than 3/4 of it. -- About 1/5 of it is Oxygen, which is the part we need. -- Water vapor can be anywhere from none to about 4% of air ... that's what makes it dry or 'humid'. -- About 1% of air is Argon. Those few gases already account for 99% of the air, but there are also tiny amounts of almost 20 other gases in it.
