condensation. you have cold air entering a very warm place (lungs) then back out to the colder environment when you breath out. same pricipal as when your windows fog up. The actual water molecule comes from the air.
humid air is lighter that an equal volume of dry air at the same temperature.
The volume of air would remain the same but the pressure of the air increased.
No: Rusting occurs by the combination of ferrous metals with oxygen from air or water, and nitrogen can not form the same compounds as oxygen does.
Air's density is less than that of water. Water's density is almost 800 times greater than air.
yes
Clouds are water suspended in air the same as mist.
no
the air mass and over lands are the same cause they are both in the same level
It is my theory that the same volume of water taken from the water bottle has to be replaced by the same volume of air. Hence the air bubble rising to replace the space left by the water.
With same mass, balloon get bigger with air than water because air is much lighter than water. With same standard volume, balloon get bigger with water than air because air is compressible and it will shrink down little bit from the pressure exerted by balloon wall.
Water vapor in the air is practically the same as measuring the humidity that is in the air.
Only in water. The air from your mouth is the same density as the air in the room- they will not float in air.
When the same amount of force is applied to a certain volume of air or the same volume of water, the air will travel faster because it is less dense.
Water because of its higher conductivity. it is the air
Need more data to answer. Are you talking about the mass of an object, neither air nor water, being the same when in the air or in the water? Yes. Are you talking about the total mass of all the air on earth compared to the total mass of all the water on earth? Definitely not.
when cold and warm air are added in the same container it causes water.
