This mixing effect is proof that the liquid molecules are moving - even when they might appear to be stationary.
A variety of weak forces act between liquid molecules to cause this effect.
In the entire gallery, made of lava, schist, and coal, it is true we found not one liquid molecule.
The liquid molecules are more attracted to other liquid molecules as compared to the polymer surface.
Experiments suggest that it has a fluid consistency and that there is movement of the liquid molecules within the membrane.
The material allows air molecules to escape but is impervious to liquid molecules.
Since gas molecules have more entropy than liquid molecules, delta S of boiling is positive.
Eventually all the liquid molecules join the crystals and you get a complete solid.
Cohesion is the force between the liquid molecules which hold the liquid together.
Adhesion is the force between the liquid molecules and the solid molecules.
