during which changes of state do atoms that cannot move past one another become free to move?\n- vaporization and sublimation\n- boiling and deposition\n- sublimation and melting\n- condensation and melting
Answer
Brief Explanations:
In solids, atoms are closely - packed and have limited movement. Melting changes a solid to a liquid where atoms can move more freely. Sublimation changes a solid directly to a gas where atoms also have high mobility. Vaporization (liquid to gas) doesn't start from a state where atoms can't move past each other (solid). Deposition is gas to solid, opposite of what we want. Condensation is gas to liquid, also not relevant to the solid - to - free - movement transition.
Answer:
sublimation and melting
