I heard of this before I think I know the answers.

1st one, I'm thinking D. Because Turning Liquid into a Solid means like it would take energy out since its freezing.

2nd one, I would choose A
B and C why would they slow down if they were still in a solid. they attracted one another, but they stood still(Didn't move). D is explaining how Liquid turns into a Solid, so this is definitely incorrect. So I would choose A.

I really do hope this helps you out. (Idk about the 1st, but 2nd I think its the answer)
