roztopiony

Roztopiony is a Polish term that translates to "melted" or "molten" in English. It describes a state of matter where a solid has transitioned into a liquid due to an increase in temperature. This process, known as melting, occurs when the kinetic energy of the particles within a solid becomes sufficient to overcome the intermolecular forces holding them in a fixed structure.

The term can be applied to a variety of substances. For example, roztopiony lód refers to melted ice, which is water. Roztopiony metal describes molten metal, a state crucial in metallurgy for casting and shaping. Similarly, roztopiona czekolada is melted chocolate, a common ingredient in desserts and confectionery. The temperature at which a substance melts is known as its melting point, a characteristic property for pure substances. When a substance cools and returns to its solid state, the process is called solidification or freezing, the reverse of melting.
