Solvation process
The mixture of a sample of C₂H₅OH and water is a solvation process ( interaction between solute and solvent ) which is a physical change and the level of solvation depends on the solvent ( water ) polarity.
The container been warm after the mixture sows that some heat is expensed into the surrounding ( exothermic reaction ). therefore we can conclude that a physical change has occurred and the solvation process is exothermic.
Hence we can conclude that the statement that best describes these observations is : A physical change occurs and the solvation process is exothermic.
