"Webb13 apr. 2024 · Melting point is the temperature at which a solid turns into a liquid. In theory, the melting point of a solid is the same as the freezing point of the liquid – the point at which it turns into a solid. For example, ice is a solid form of water that melts at 0 degrees Celsius/32 degrees Fahrenheit and changes to its liquid form. " - Theoretical melting point
