Webcondensation, deposition of a liquid or a solid from its vapour, generally upon a surface that is cooler than the adjacent gas. A substance condenses when the pressure exerted by its vapour exceeds the vapour pressure of … WebPhase Changes. Melting is defined as the process of converting a substance from the solid to the liquid state of matter. A chemical that exists in its liquid state can be changed back into a solid state in a process known as fusion, which is more commonly-known as "freezing."

WebNov 5, 2024 · Phase changes are physical transformations of a substance from one phase to another. The transformation typically takes place at a specific temperature, also referred to as the substance’s melting or boiling point, when heat is applied or removed. In other words, when a substance gains or loses energy, molecules or atoms either move closer ... Webvaporization, conversion of a substance from the liquid or solid phase into the gaseous (vapour) phase. If conditions allow the formation of vapour bubbles within a liquid, the vaporization process is called boiling. Direct conversion from solid to vapour is called sublimation.
