Question

For which of the following processes would there decrease in entropy?

A. melting ice
B. separation of a compound
C. boiling water
D. freezing water

Answer 1

Entropy is basically a measure of how organized or disorganized energy is in a system of atoms/molecules.
Melting ice, decomposing a compound, and boiling water all cause a greater dispersal of energy, and so for them entropy is increasing.
hope this helps
