The order of temperature at which three oxides will melt when they are placed side by side in solid state and the temperature is raised is to be stated. Concept introduction: The melting point of a solid substance is defined as the temperature at which it changes state from solid to liquid. At the melting point, the solid and liquid phase of the substance exists in equilibrium with each other. Therefore, the solid having a lower melting point will melt at a lower temperature.
