The useful idea
- The useful idea
Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point.
- How it works
For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures.
- Why it matters
For example, agar displays a hysteresis in its melting point and freezing point.
Why this matters
Look for Freezing the next time you notice this pattern in everyday life.
