Air is technically loosely formed molecules made up of hydrogen, carbon dioxide, and other misc. elements. Air is so loosely formed that you push the air molecules out of your way when you walk. this is why air can push you back at high speeds.
A perfect vacuum is a space devoid of any matter, including air. It differs from other types of vacuums, such as household vacuums, which remove air and debris from a confined space but do not achieve a complete absence of matter.
It differs by the amount of buoyancy the rock contains. In the air it is much more heavier. In space, it is much more buoyant. But if let off of the scale in water, it would plainly sink, and if let off the scale in space, it would float away into the universe.
Yes.
you don't need air in space because there is no air in space at all! but in space they do have really small gravity!
There is no air in outer space.
Yes,air occupy space
If there was AIR in space, why would Astraunots wear big helmets for air?!?!
In space, sound cannot travel because there is no medium for it to propagate through. In a medium like air or water, the speed of sound varies depending on the density and elasticity of the medium. In general, sound travels faster in solids, slower in liquids, and slowest in gases like air.
if there was air in space space men would not need suits and oxygen
No air The space suit has air bottles
In space, there is no air, and its pressure is Zero.
Earth does have air while the space does not have air.
