If a material has a melting point of 100°C, what state will it be in at 50°C?

A material with a melting point of 100°C indicates that it transitions from a solid state to a liquid state at that temperature. Therefore, at a temperature of 50°C, which is below the melting point, the material remains in its solid state. In general, solids maintain their form and structure at temperatures lower than their melting point. As a result, at 50°C, the material would still be solid and not have undergone any phase change.
