smältområdet
Smältområdet refers to the temperature range over which a solid substance transitions into a liquid. This is a characteristic property of a substance, meaning it is unique and can be used to identify it. For pure crystalline solids, the melting process occurs at a single, sharp temperature, known as the melting point. However, for amorphous solids, such as glass or many plastics, melting is a more gradual process occurring over a range of temperatures. This is because their molecular structure is disordered, allowing for a progressive softening rather than a sudden liquefaction.
The smältområdet is influenced by several factors, including pressure. Generally, an increase in pressure raises the
