WebMelting - solid to liquid. When a solid is heated, its particles gain enough energy to overcome the bonding forces holding them firmly in place. They start to move about, but stay close to their neighbouring particles, rolling around each other. This particle movement allows the substance to flow and form a liquid. WebFreezing is a phase transition where a liquid turns into a solid when its temperature is lowered below its freezing point.In accordance with the internationally established …
WebSo the freezing temperature is lower for a solution. I mentioned the equilibrium freezing and boiling temperatures above. Time to explain. Imagine ice floating in pure water at 0°C. If we add a little heat, some ice melts. Remove a little heat and some water freezes. We call this the equilibrium freezing temperature: 0°C for water.
