We can see that points A, B, C and D are all still coplanar points. Point E is not coplanar with the original four points. But if I pick any group of three of the points, even a group containing point E, those three points will be coplanar. The reason is the statement given above - any three points in 3-dimensional space determine a plane.
Definition of solubility. 1  1 : the quality or state of being soluble. 2  2 : the amount of a substance that will dissolve in a given amount of another substance.
All sorts of things can change the concentrations of substances in solution. Scientists use the word solubility. Solubility is the ability of the solvent (water) to dissolve the solute (sugar). You may have already seen the effect of temperature in your classes. Usually when you heat up a solvent, it can dissolve more solid materials (sugar) and less gas (carbon dioxide). If your friend was mixing sugar and water, she would be able to dissolve a lot more sugar into hot water rather than cold.
