Sagot :

Final answer:

A horizontal line on a heating curve indicates a change of state where temperature remains constant during a phase transition.


Explanation:

A heating curve displays temperature changes over time as heat is added to a substance, showing transitions between solid, liquid, and gas states. In a heating curve, a horizontal line indicates a change of state where the temperature remains constant during a phase transition, such as melting or boiling.

For example, at the melting point, a substance shifts from solid to liquid state, and the temperature stays constant until the phase transition is complete. This feature of a horizontal line on a heating curve signifies a change of state rather than a change in temperature.
