Question

Statement 1: Entropy of ice is less than water.
Statement 2: Ice has cage-like structure.

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation of the statement 1 .
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1 .
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true.

Answer 1

Answer: (B)

Entropy of ice is less than water because water molecules in solid state lose kinetic energy and hence their tendency of movement is minimised. Hence entropy decreases in solid state. The statement 2 that ice has cage-like structure is alsocorrect but statement 2 is not the correct explanation for statement 1.
