Basic concepts and example in entropy (physical chemistry)

Basic concept and example in entropy. An endothermic process with a loss of entropy: (An Reaction which absorbed energy and result formation of more order substances/compounds) Recrystalistaion: In order to dissolved the crystals in the solvent, energy is required to be put into system in the form of heat, (increasing the kinetic energy of the system to dissolved the impure crystals .As the kinetic energy of the system increased,( the molecules within the solvent …

…a result of the evaporation. The entropy of the system, there is a net gain in entropy of the system since the result, is increase in the number of disorder component of the system. (The water vapour is in it excited state will eventually dissipate the excess energy and will change back to liquid phase via condensation) (The amount of energy supply is less than that of the energy given out therefore an endothermic reaction)
