Breaking down of something into parts: The separating,decomposing, or disintegrating of something into smaller or more basic constituents.
What Is Dissolution?
Process of dissolving a solute in a solvent is called dissolution. Preparation of a solution does not involve any chemical reaction. The insolubility of gases in liquid solvents can easily be understood. Gas molecules are far apart, so they have negligible attraction for each other. They will develop weak attractive forces for solvent molecules as well. Obviously gases will have lesser solubility in liquid solvents. The solubility of gases in liquid solvents depends on pressure, greater the pressure the greater will be the solubility. On the other hand if a gas readily dissolves in a liquid solvent atmospheric pressure, then it will be due to a chemical reaction.
Cohesive forces are present not only among solute molecules but solvent molecules as well. These forces are responsible for keeping the molecules of a substance together. The process of dissolution can occur only if these cohesive forces among solute molecules are weakened appreciably by the new forces of attraction between solute and solvent molecules. Energy is both absorbed and evolved in this process. If the amount of energy needed to break the cohesive forces among solute molecules.
Energy is both absorbed and evolved when new forces are created, the process of dissolution will take place by absorption of heat. Conversely, heat is evolved if the forces of attraction between solute and molecules are stronger than the cohesive forces. Water is an excellent solvent. It dissolves almost everything in it. It has strong cohesive forces present in it. Water dissolves a solute due to its characteristics.

On the other hand if a gas readily dissolves in a liquid solvent at atmospheric temperature, then it will be due to a chemical reaction.Cohesive forces are present at only among solute molecules but solvent molecules as well. These forces are responsible for keeping the molecules of a substance together. The process of dissolution can occur only if these cohesive forces among solute molecules are weakened appreciably by the new forces of attraction between solute and solvent molecules.
Energy is both absorbed and evolved in this process. If the amount of energy needed to break the cohesive forces among solute molecules exceeds the energy evolved when new forces are created, the process of dissolution will take place by absorption of heat.
