The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-step Solution: **Step 1: Analyze the Assertion** - The assertion states that the dissolution of sugar in water proceeds via an increase in entropy. - When sugar dissolves in water, it breaks down into individual sugar molecules (or ions, depending on the type of sugar), which increases the number of particles in the solution. - The increase in the number of particles leads to greater disorder in the system, which is a key characteristic of entropy. - Therefore, the assertion is **True**: the dissolution of sugar in water does indeed result in an increase in entropy. **Step 2: Analyze the Reason** - The reason states that entropy decreases when an egg is hard boiled. - When an egg is boiled, the proteins within the egg undergo denaturation, which means they unfold and lose their structured arrangement. - This unfolding of proteins increases the randomness of the system because the proteins go from a more ordered state to a less ordered state. - Therefore, the statement about entropy decreasing when an egg is hard boiled is **False**: in reality, the entropy increases as the proteins unfold and the system becomes more disordered. **Step 3: Conclusion** - Since the assertion is true and the reason is false, the correct answer to the question is that the assertion is true but the reason is false. ### Final Answer: - Assertion (A) is True. - Reason (R) is False.
