Molecular formula :
nature : the material is crystalline and liquid balance coexistence temperature. Sometimes also called melting point. Crystal suffered the melting point and the pressure. For example, each additional 0.1MPa, ice melting point about the decline 0.000745 ° C Under some pressure, and the crystal melting point and its solidification point the same. For amorphous (such as glass), there would be no melting point, only softening temperature range.
