because they need room for the particles to move around
The gasses are compressed mainly so they can fit in a smaller space. If the gasses were not compressed it would be very inconvenient and costly to reserve the space for the quantities of gas needed.
gases tend to take up the entire space they are given. if a little is in a large area, density will be low, but even throughout the entire area its given. it will also cause suction. if there is a lot in a small area, it will be high density, and will add a lot of outward pressure to its container. basically, gasses do take up space, but they will move to accept other objects, and take up all of the space they are given. so, the i guess the answer is: all of it, but none of it. hope that helped ^^
Like all gasses, nitrogen takes up space, so when nitrogen is put into a given area it pushed other gasses, including oxygen, out of the way.
Yes, but not so much. Use your storage space wisely.
lol i dont even know
about 52 acres if it is a big one if not then say so
You have to overcome the force of gravity. So, if you're in the space shuttle which weighs 240,000 pounds at liftoff, you have to have enough force to overcome that weight.
gasses take up the entire volume of their containers regardless of their molecular size. The intermolecular space is so huge that their molecular mass is negligible in comparison.
there is so much open space
It depends on the size of the cage. They will take a bit of space but not so much that you will get annoyed with it. Maybe about half/a quarter of a room or so.
Because its much cheaper, makes you healthier, they take less space then cars.
There is nothing toxic about hydrogen or helium and there is no reaction that occurs between them. However, like all gasses they take up space and so can displace oxygen from an area. A lack of oxygen can kill a person in minutes.
