NEET Chemistry Entropy MCQ Question

Type: MCQ-conceptual-Hard-Class 11

Which of the following combinations correctly describe the effect of entropy in a system?

A

A liquid crystallizing into a solid results in decreased entropy. Raising the temperature of a crystalline solid from 0 K to 115 K results in increased entropy.

B

A liquid crystallizing into a solid results in increased entropy. Raising the temperature of a crystalline solid from 0 K to 115 K results in decreased entropy.

C

A liquid crystallizing into a solid has no effect on entropy. Raising the temperature of a crystalline solid from 0 K to 115 K has no effect on entropy.

D

A liquid crystallizing into a solid results in increased entropy. Raising the temperature of a crystalline solid from 0 K to 115 K results in increased entropy.

Correct Answer

Option A

Detailed Explanation

When a liquid crystallizes into a solid, the molecules attain an ordered state, leading to a decrease in entropy. Conversely, raising the temperature from 0 K to 115 K causes the particles to move, resulting in an increase in entropy.
