Explanation:

Yes, phase - change of matter occurs when the same molecules change states. For example, water molecules can exist as ice (solid), liquid water, and water vapor (gas). Heating or cooling causes changes in the energy of the molecules and their intermolecular forces, leading to state changes.

Answer:

Yes. An example is water molecules which can be ice (solid), liquid water, or water vapor (gas).
