Question

What was happening to the entropy of the system as the ice melted? It was increasing a lot. It was increasing a little. It was staying about the same. It was decreasing a little. It was decreasing a lot.

Answer 1

Answer: It was increasing a lot.

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

When ice is melted,  In this reaction solid is converting to liquid phase. The randomness will increase  as the intermolecular forces decrease and the molecules move away from each other and hence entropy will also increase.
