The correct Answer is:
To analyze the given statements, we will break down the assertion (A) and the reason (R) step by step. ### Step 1: Understanding the Assertion (A) **Assertion:** "Dissolution of sugar in water proceeds via increases in entropy." - When sugar is added to water, the sugar molecules interact with water molecules. - The strong intermolecular forces (like hydrogen bonds) between sugar molecules are overcome, and the sugar molecules disperse throughout the water. - This process leads to an increase in the disorder of the system because the sugar molecules are now spread out rather than being in a solid state. - Therefore, the dissolution of sugar in water results in an increase in entropy. ### Step 2: Understanding the Reason (R) **Reason:** "Entropy decreases when an egg is hard-boiled." - When an egg is raw, the proteins (like albumin) are in a complex, folded structure. - Upon boiling, these proteins denature, meaning they unfold and lose their structured form. - This unfolding increases the randomness of the protein molecules, leading to a higher degree of disorder in the system. - Thus, the entropy actually increases when an egg is hard-boiled, contrary to the statement provided. ### Step 3: Conclusion - The assertion (A) is true because the dissolution of sugar in water does lead to an increase in entropy. - The reason (R) is false because boiling an egg increases the entropy, not decreases it. ### Final Answer - **Assertion (A) is true, and Reason (R) is false.**
