Felolvadni

Felolvadni, also known as melting, is a physical process in which a solid substance is transformed into a liquid state. This transition occurs due to the application of heat, which increases the kinetic energy of the particles within the solid, causing them to overcome the forces holding them in a fixed position. The temperature at which a substance melts is known as its melting point.

The process of melting is endothermic, meaning it absorbs heat from its surroundings. This heat energy is used to break the intermolecular forces that hold the solid particles together. Once the melting point is reached, the solid and liquid phases coexist in a state known as a phase change or phase transition.

Melting is a reversible process. If the liquid is cooled below its melting point, it will solidify again, releasing the heat it absorbed during the melting process. This is known as freezing or solidification.

Melting is a common phenomenon observed in everyday life. For example, ice melts into water when heated, and wax melts into a liquid when heated above its melting point. In industrial settings, melting is used in processes such as metal casting and glass production. Understanding the principles of melting is crucial in various scientific and engineering disciplines.
