PLEASEE HELPP!

Which of the following changes would show a decrease in energy?
A.gas to plasma
B.solid to gas
C.liquid to gas
D.liquid to solid

Which of the following is true about a change from a solid to a liquid?
A.The particles speed up.
B.The particles slow down.
C.The particles remain at the same energy level.
D.The particles get closer together.

Answer 1

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)
