A. solid ice has a more rigid structure; therefore, dS decreases.
B. O2 @ 800 K has more random ways to interact with each other; therefore, dS increases.
C. Your turn. In dS problems like this remember to look at the ransomness of the molecules.

So for C, dS would increase since gas form is less structured than liquid?
