Given what we know, we can confirm that the time in which a solid phase and the liquid phase of an object are in perfect equilibrium is during the time that the temperature remains at the melting point of the substance.
What do we know about phase equilibrium ?
- This refers to a substance being both a solid and a liquid at the same time.
- This happens when a substance is melting.
- Therefore, when the temperature reaches the melting point, we are at an equilibrium between solid and liquid phases.
- We do not have access to the graph mentioned, but by studying how long the temperature was at the melting point, we will know the answer.
Therefore, we can confirm that phase equilibrium refers to the time in which a substance is both in a solid and liquid state. This can be achieved during the melting of a substance and so the equilibrium state happens at the melting point.
