Hey KYH,
we asked for it and you delivered....
Patch is right about osmosis: Only water travels thru a membrane to dilute the more concentrated salted water.
If you take a U-shaped pipe with a water permeable/salt impermaeble membrane at the bottom, Fill one side with pure water and the other with salted water. The column of pure water will drop and the column of salted water will rise. The height difference is the osmotic pressure (or force).
Hot water/cold water columns in this device will stay in equilibrium height wise so no osmotic pressure present.
Great story nonetheless about how Congress solve the embarrassing conclusion of the proceedings i.e. de-mons control chemical migrations in plastic by inventing a scientific effect that suits their purpose. The Gilbert effect is one sided only....
Typical!
