For a substance to change from a solid to a liquid, what must happen to its particles?
A. They must gain enough kinetic energy to break out of their rigid
structure and move independently.
B. They must lose enough of their kinetic energy that their motion is
influenced by the attractions between them.
C. They must lose enough of their kinetic energy so that the
attractions between them hold in place as they vibrate.
O D. They must gain enough kinetic energy to allow them to move
freely while still being attracted to one another.
