When a substance gains or loses energy, it’s changes, or its chafes. theses two changes do at the time ; the temperature remains the change of complete.

When a substance gains or loses energy, its temperature or state changes. These two changes do not happen with respect to time; the temperature remains the same until the change of state is complete.

Explanation:

This statement is about energy and change of the state of the matter. By gaining or losing energy, the physical state of the matter can change into one another. Melting, freezing, condensation, evaporation, sublimation, and deposition are the processes that support to change the physical state of the matter. Change in state and change in the matter do not happen at the same time. A substance gains or loses energy to reach a specific temperature and remains constant until the physical change of matter is completed.
