Weegy: #2 shyboy shyboy is Offline: Posts: 142 none of the really rely on the electrostatic effects. That means that we do not need to know anything about electricity to explain them. [ What is important is that the liquid molecules may collide to each other. The upthrust comes from the fact that liquid has no shape. So at the equilibrium the pressure on the piece of liquid is the same in all directions. That is pure mechanics, the potential, elastic and kinetic energy are players there. The viscosity comes from thermodynamic. The important player in this game is thermal energy. Now the process becomes irreversible. That is kind of tricky and non-trivial- you need to use reversible mechanical equation to introduce irreversibility. Without going into deep, you may just use known thermodynamical equations. friction heats. ]
