Web8 sep. 2024 · Answer: 1. Sublimation: C 2: Melting: B 3: Freezing: D 4: Evaporation: A Explanation: In the lesson, we learned that Sublimation is like a solid turning into gas (vapor). For melting, we learned that it is a solid that turns into a liquid, example of melting is snow turning into water. Web13 aug. 2024 · The melting point (or melting temperature) is the temperature at which a substance changes from a solid to a liquid state. Fusion is a property in which an element passes from the liquid phase to the solid phase.

Melting • Phase change from a solid to a liquid • Molecules speed up, move farther apart, and absorb heat energy. 7. Freezing • Phase Change from a liquid to a solid • Molecule slow down, move closer together and release heat energy. 8. Vaporization (Boiling) • Phase change from a liquid to gas. consultative selling book
