You were all over the place
Was not.
, spouting contradictions to your own position
Point out one. Just one.
, all the while thinking you were bolstering it.
Hopefully after my last post you can rein yourself back in.
Let's see:
Which negates the air column theory.
Gas molecules expand in all directions filling up available space.
Gas molecules don't expand, they are at their same size once they become gas. As liquids they are much more compact and as gas they are 'ballooned' up in effective size, but this is the only expansion they undergo.
Ergo, air molecules since they are already gaseous, have already expanded to their gaseous size; their velocity increases with temperature.
What you mean is that gases (bulk quantity of gaseous molecules) expand, and what you're getting at, is that all the air in the atmosphere should just expand off into outer space, and I'm telling you that the air pressure at sea level basically serves as a container, a container with 14.7 PSI pressure, so every molecule of air at sea level is met with this same pressure in all directions. It can go up and down and sideways all basically to the same degree.
Although, it is true, that with increasing elevation, there is a decreasing pressure, so there is a slight gradient in pressure going down as you get higher up, and rising as you drop to below sea level like in Death Valley.
They're not stopping after travelling 1 inch sideways.
Sure they are, even before that since they'll encounter another air molecule before they make it 1 inch, they'll bounce off a few different molecules in that span at least is my guess.
Not only that their very action negates any influence that could be attributed to gravity as a force.
No, because why is the pressure there at all? To your point, there's no container here, so how is there so much absolute pressure at sea level? It's because of gravity.
You can't have or measure pressure without a container.
That's just false lol.
You just whipped your own argument again.
How ya gonna have 14 pounds of sideways pressure into the side of your leg if you've got a 14 pound column of air running down beside your leg?
Because pressure is omnidirectional force.
No.
That's why I detailed the experiment, fingers on the ground , ice cube on your fingers.
Leaves no room for expanding air molecules to help with the lift.
There're no expanding air molecules, see above. There's just pressure.
You measure the amount of force it takes at the beginning of the lift.
The only physics equation you need is it takes an equal amount of force before you can even begin to push back against another force.
And you lifted the ice cube. So it took some work. And now the ice cube has more potential energy than it did before, because you did some work.
