There is measurable atmospheric pressure at the earth's surface. The pressure must be coming from something. Air offers resistance to movement independent of the effects of acceleration. It also supplies thrust and lift to aircraft; the movement of aircraft would be hard to explain without air.
Fill a tub with water, take a piece of paper and cup, then tape the paper inside the empty cup. then put the cup in the tub(filled with water) up side down, after taking it out you should see that the paper is still dry. This proves that air exist because it got trapped into the cup which kept the paper dry.
Thank you!
Air has mass; You get a balance, blow up a balloon, put it on one end, another balloon that you didn't blow up, on the other end. Air occupies space; Get a cup, turn it upside-down then submerge it into a basin of water. So air is matter. :)
Something that occupies space and has mass is known as Matter. As Air occupies space, and also has mass, it should be Matter
The presence of the air may be felt as the wind or from a fan.
Need to know what your question is.
Need to know what the problems are.
Albert Einstien was the first to detect the presence of magnetic field in earth
i think i know from my science teacher... Since Liquid, and solids sometimes
as far as i know, the 2000 sport does not have one--at least mine doesn't!!
Pneumothorax-presence of air or gas in the pleural cavity.
* We all know that Aerobic means in presence of air. * when a culture medium is kept outside in presence of air to grow is considered as growth in aerobic medium. * Simply it can be called as the growth of culture media in invibo condition but not in invitro condition.

1) The air needs to be cooled to its dew point. 2) The air needs to have reached saturation, which can be achieved through many ways.
The presence of dust in the air expedites cloud formation. This is because the water droplets stick to the dust.
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
air bladder is present which regulates buoyancy
air is paramagnetic and this caused by the presence of O2 which is paramagnetic as it has 2 unpaired electrons.
Increases Density
Pneumocrania is Pneumocephalus ... The presence of air in the intracranial cavity.
Air has no effect on gravity. But the presence of air can change the response of an object to the force of gravity alone.
Heating an orc to a high temperature in the presence of air is a long process. It is when heat is transfer through atoms or molecules that move.
