The increase in entropy can be best represented by option A: Thawing.
Here's a brief explanation:
1. Entropy is a measure of the randomness or disorder in a system.
2. When something is thawing, like ice melting into water, the molecules are becoming more disordered and spread out.
3. As a result, the entropy of the system increases because the molecules move more freely and occupy more space in the liquid form compared to the solid form.
Therefore, thawing represents an increase in entropy because it involves a transition from a more ordered state (solid ice) to a more disordered state (liquid water), leading to an increase in randomness or disorder within the system.
