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.
Definition of Solubility of Gases. The amount of a gas which will dissolve in a liquid chiefly depends upon the gas pressureâthe greater the gas pressure, the greater its solubility. Gas solubility will be even greater if the gas reacts with the solvent, e.g., ammonia and carbon dioxide in water. Gas solubility is quantitatively described by Henryâs law, which states that the amount of a gas dissolved in a liquid at a fixed temperature depends only upon the gas pressure. This is true for both pure gases and mixtures of gases.
