jääpiste

Jääpiste refers to the temperature at which a liquid freezes into a solid. For pure water at standard atmospheric pressure, this temperature is defined as 0 degrees Celsius (32 degrees Fahrenheit). The freezing point of a substance is a characteristic property and can be used for identification. Impurities in a liquid can significantly lower its freezing point, a phenomenon known as freezing point depression. This principle is utilized in applications like using salt to melt ice on roads. The process of freezing is a phase transition from a liquid state to a solid state, involving the release of latent heat. Conversely, the melting point is the temperature at which a solid transitions to a liquid, and for a pure substance, it is the same as its freezing point. Understanding the jääpiste is crucial in various scientific and engineering fields, including meteorology, chemistry, and materials science.
