Which statement is correct?
Natural processes happen spontaneously when they decrease the entropy of a system because entropy increase is counteracted by the flow of enthalpy from high temperatures to low temperatures.
Dissolving table salt (NaCl) in water leads to a decrease in entropy because salt particles, which are numerous individual crystals in solid form, become a homogenous solution in water.
Any change that increases the number of particles in a system increases entropy because it increases the randomness and disorder of the system.
Among solids, liquids, and gases, solids generally have the highest entropy because solid particles are the least mobile, and entropy is inversely related to mobility of particles.
