The melting point of a substance is equivalent to its
Answer Details
The sentence is stating that there is a relationship between the melting point of a substance and some other property that is not specified in the given sentence. The sentence is asking to complete this relationship.
The correct option that completes this relationship is "Solidification Temperature". The melting point of a substance is the temperature at which it transitions from a solid state to a liquid state. Similarly, the solidification temperature of a substance is the temperature at which it transitions from a liquid state to a solid state. These two temperatures are the same for a given substance, which means that the melting point of a substance is equivalent to its solidification temperature.
Therefore, the correct completion of the sentence would be: "The melting point of a substance is equivalent to its Solidification Temperature." The other options provided in the question do not complete this relationship and are therefore incorrect.
