Question

donna is studying phase changes. she claims that since the three phases have different amounts of energy, molecules in substances gain or lose energy only during phase transitions. what is incorrect about this claim? molecules gain or lose energy during any temperature change, not just phase changes. molecules do not have any energy changes, because they have a set amount of energy all the time. molecules are constantly losing energy, no matter what phase change is happening. energy levels are not related to phase changes.

Explanation:

Molecules' energy changes with temperature. It's not limited to phase - transition times. When temperature rises or falls, kinetic energy of molecules changes.

Answer:

Molecules gain or lose energy during any temperature change, not just phase changes.
