Final answer:

When a substance is changing state, its temperature remains constant until the phase change is complete.


Explanation:

The temperature of a substance remains constant when it is changing state. During a phase change, such as from solid to liquid or liquid to gas, the energy is used to break or form intermolecular forces rather than increase the temperature.

For example, when ice at 0°C is heated, it melts to water at 0°C. Only after the entire phase change is complete, will the temperature increase.

Understanding this concept helps explain why during state changes, the temperature stays the same until the transition is finished.
