I see. Would you please help me understand. How is your question: "If air is condensed or frozen, does it not weigh more than before?" related to your citation: "A tank filled with compressed air will weigh more than a tank that is filled with air at normal atmospheric pressure." Isn't there more air in the first case than the second?
I think that you should have cited this from that reference: "Since weight is the measure of an object's gravitational pull, the compressed air does not weigh more."
Yes, if a ton of air is condensed, that same ton of air, would still weigh the same. It would just be in a much smaller area of occupation.
It's your fault for misunderstanding my question, see?
Nitrogen that is very dense, in liquid form, weighs more than normal air nitrogen. It's more dense and affected more strongly by the EM acceleration from above, thus pushed down more strongly.
So gas density of whatever element is directly proportionate to how much it's being forced down by the air above it.
Just like colder air "falls down" from upper layers of air, because it dislodges the less dens air, which more easily rises to the surface, that colder air, with higher density is in fact more "in tune" with the EM force that pushes it down.
Since both Magnetism is weakened and dissabilitates by high temperature, and highly effective in COLD or lower temperatures, the air's EM that has a downwards sense of direction, has the EXACT SAME PROPERTY.
When that air is very cold, the "gravitational" electromagnetism from above it, is the most effective, and pushes it down the easiest.
When that same air is very hot, it's magnetism is weakened to the point the "Upper Magnetism" that should force it down, is less effective, and thus it appears to weigh less.
If both metalic Magnetism and air Magnetism have the same "cool preference" and "warm weakness", how then could they not be the same force?
If you can't even understand how magnetism works, you are an utter tool. And not even a metalic or magnetic one.
..... You're an imagnetic tool.
