In which of the following changes, entropy decreases?
- A Rusting of iron
- B Melting of ice
- C Vaporisation of camphor
- D Crystallisation of sucrose from solution
Answer & Solution
Correct Answer
(D) Crystallisation of sucrose from solution
Step-by-step Solution
Detailed explanation
Among the given options, entropy decreases during the crystallisation of sucrose from solution. It is because entropy is a measure of randomness and during the process of crystallisation liquid state changes into solid state. Hence, entropy decreases.
