i think its c?

justjm · Answer

I believe so, because of the stable gravitational potential energy, which is supposedly at height, is falling and converting to KE.

-Building a house of cards: not much change in energy

For freezing something or condensing something, ∆S, entropy, is always negative. So that's out.
