Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point.[1][2]

For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures. For example, agar displays a hysteresis in its melting point and freezing point. It melts at 85 °C (185 °F) and solidifies from 32 to 40 °C (90 to 104 °F).[3]
