Heat evolved/absorbed during conversion of a substance from one allotropic form to another is termed as the heat of______________?
Correct answer: D. Transition
- A. Fusion
- B. Vaporisation
- C. None of these
- D. Transition
Explanation
The heat absorbed or released when a substance changes between two allotropes is called the heat of transition. Fusion and vaporisation specifically refer to solid-liquid and liquid-vapour changes, respectively.
