Smältprocessens

Smältprocessens refers to the process of melting, which is a phase transition where a solid turns into a liquid due to an increase in temperature. This occurs when the thermal energy of the atoms or molecules in a solid becomes high enough to overcome the forces that hold them in a fixed, rigid structure. The temperature at which this transition happens is known as the melting point, and it is a characteristic property of a pure substance under a given pressure.

During melting, the added heat energy is used to break the bonds between particles in the solid, rather than to increase their kinetic energy, so the temperature remains constant at the melting point until all the solid has melted. Once melted, the liquid substance can flow and take the shape of its container. The reverse process of melting is freezing, where a liquid turns back into a solid at its freezing point, which is the same temperature as the melting point for a given substance. Understanding smältprocessens is fundamental in various scientific and industrial applications, including metallurgy, materials science, and chemical engineering, as it dictates how materials behave under thermal stress and how they can be shaped and processed.
