Name the heat that is involved in the conversion of one allotropic form into the other.

Explanation

**Step-by-Step Solution:**

1. **Understanding Allotropes**: Allotropes are different forms of the same element, where the atoms are bonded together in different ways. For example, carbon can exist as graphite or diamond.

2. **Defining the Heat Involved**: The heat involved in converting one allotrope to another is specifically referred to as the "enthalpy of transition." This term describes the heat energy required for the transformation between different allotropes.

3. **Example of Allotropic Conversion**: A common example of this process is the conversion of graphite to diamond. This transformation requires a significant amount of energy.
