Crystallization of sucrose from solution

Vedclass · Answer

(A) Entropy is a measure of the randomness or disorder of a system. $(A)$ Crystallization of sucrose from solution involves the transition from a disordered liquid state to an ordered solid state,which results in a decrease in randomness and thus a decrease in entropy. $(B)$ Rusting of iron involves the formation of a solid oxide from iron and oxygen gas,but it is generally an exothermic process that increases the entropy of the surroundings,and the overall process is complex. $(C)$ Melting of ice involves the transition from a solid to a liquid,which increases randomness and entropy. $(D)$ Vaporization of camphor involves the transition from a solid to a gas,which significantly increases randomness and entropy. Therefore,the correct answer is $(A)$.

In which of the following processes does entropy decrease?
