Absorption/evolution of heat during conversion of a substance from one allotropic form to another is termed as the heat of _____________________?
Correct answer: C. Transition
- A. Sublimation
- B. Fusion
- C. Transition
- D. Vaporisation
Explanation
A change from one allotrope or solid form to another is a phase transition, and the associated heat is called the heat of transition. Fusion, vaporisation, and sublimation refer specifically to solid-liquid, liquid-vapour, and solid-vapour changes.
