What is the process of dissolution

At which rate in the solvent there is a solute change in the molecule dispersion from, powder, liquid, crystal or other states, it is known as dissolution rate. Solubility is the quantity of solute, which can be molecularly dispersed in a certain amount of the solvent. The dissolved solute in a liquid should be available only in a liquid condition because the solutions do not occupy the fixed position in relation to the ions or molecules of the solution and so, it cannot be supposed in a solid state. In a solvent, the solution involves a change in the solution of the solute along with the solvent in the transfer of soluble molecule. Molecules of Solute are separated from other molecules and make space for adjusting solute molecules. Therefore, the decomposition will occur only when the solvent and solute are mutually attracted to a degree which is sufficient to overcome the interactional attraction forces between solute-solute for solvent-solvent and solute-solvent interactions. Although these contributions force can be quite different in strength. 
Attractive forces planted between polar molecules are quite strong compared to those present between polar and non-polar molecules. Therefore, in polar solute with admirable intermolecular interactions, the transfer of solute molecules in the solution occurs only when the solvent like water is also polar since non-polar solvents such as benzene will be unable to attract adequate attraction on the molecule so that the separation from the other solute molecules. 
As opposed to this, the intermolecular attraction of non-polar substances such as paraffin wax is relatively weak, therefore, dissolution of such substances occurs when solvent-solute integration is stronger than solvent-solvent interaction. Between polar solvent molecules, a marked intermolecular association such as water is used to prevent the dissolution of a non-polar solute and therefore, solute tends to be controlled to the non-polar liquids such as benzene. 
The above thought can be summarized as if a non-polar solvent dissolves a non-polar solute and polar solvent dissolves a polar solute. Though, this overview should be used with concern as the intermolecular interaction concerned with the dissolution process is influenced by factors that are not responsible for the polarity of the molecule.
