Question

What is the change in the entropy of water, When ice melts into water?

• A. Entropy of water becomes zero.
• B. Entropy of water remains same
• C. Entropy of water decreases
• D. Entropy of water increases.

Answer 1

The correct option is D

Entropy of water increases.

Entropy is a measure of the disorder or randomness of the system. The greater the randomness in a system, greater is its entropy. The randomness is greater in liquid state as compared to solid state so the entropy increases when ice melts into water.
