jähmettymispisteensä

Jähmettymispisteensä refers to the point at which a substance transitions from a liquid to a solid state due to a decrease in temperature. This temperature is a characteristic property of a pure substance and is often referred to as its freezing point. At this specific temperature, the kinetic energy of the molecules within the liquid is no longer sufficient to overcome the intermolecular forces holding them together. As a result, the molecules arrange themselves into a more ordered, crystalline structure, forming a solid.

The jähmettymispisteensä is also the same temperature at which a solid will melt into a liquid, assuming no impurities are present. This reversibility is a fundamental aspect of phase transitions. Factors such as pressure can influence the jähmettymispisteensä, although the effect is generally less pronounced than for the boiling point. For example, water's freezing point decreases slightly with increasing pressure, which is why ice skates glide so easily. Impurities dissolved in a liquid typically lower its jähmettymispisteensä, a phenomenon known as freezing point depression, which is utilized in applications like salting roads in winter.
