The ideal gas law states that pressure (P) is equal to the product of density (N), the ideal gas constant (R) and temperature (T):
P = N x R x T
I can't figure out which unit the pressure is actually in, although it does seems to work out as the figure I'm supposed to get with a 11706.85°...
Well I assembled an airtight and almost completely vibrationless apparatus to test this theory (small brass nozzle mounted into the lid of a large upturned glass jar which I sat atop a drinking glass on a concrete slab.)
Then I added salty water to my jar-'straw', which didn't seem to have any...
Why is it that a straw with it's top blocked off retains a liquid while an upside down bottle will release it?
Is it because the cohesion of the liquid in an area so small will prevent air from passing up through the liquid and replacing it within the straw?
If this is the case I intend to...
