When does the level of solution stop rising?

The level of solution stops rising when the solute can no longer dissolve in the solvent at a given temperature and pressure, reaching saturation. At this point, a dynamic equilibrium exists between dissolved and undissolved solute particles in the solution.


Why does the level of a more concentrated solution rise when two solutions of different concentrations are separated by a semipermeable membrane and when does it stop rising?

The more concentrated solution is hypertonic and osmotic pressure (a hydrostatic force whose sole purpose in life is to make concentrations equal) tends to move solvent into the more concentrated solution. It will stop rising when either a) the solution concentrations are the same on both sides of the membrane, or b) when the osmotic pressure becomes equal to the ambient air pressure.


Why does the toys can stop before it begins to roll back to you?

Friction and air resistance. All of its kinetic energy gets converted to heat.


If a marble is in a tube starting as potential energy and turns into kinetic energy but the marble goes in a loop and goes to a stop what type of energy is that called?

You have converted potential energy to kinetic and then back to potential. If the marble came back exactly to its starting point you would have invented perpetual motion, but in fact it will lose a little energy in friction against the tube so it will gradually lose energy and eventually just stop at the lowest point of the tube.
