Freezing Point
The Freezing Point (pronounced: /ˈfriːzɪŋ pɔɪnt/) is a fundamental concept in Thermodynamics and Physical Chemistry. It refers to the specific temperature at which a substance changes from its liquid state to its solid state under normal atmospheric pressure.
Etymology
The term "Freezing Point" is derived from the English words "freeze" and "point". "Freeze" comes from the Old English "freosan" which means "to turn to ice", and "point" comes from the Latin "punctum" meaning "dot, particle, speck".
