WebAnswer: Melting Points. The temperature at which a solid melts is known as the melting point (MP) of that substance. The. melting point is a physical property of a solid and can be used to help identify a substance. In. practice, a solid usually melts over a range of temperatures rather than at one specific. WebMelting point determination starts at a predefined temperature close to the expected melting point. The red solid line represents the temperature of the sample (see figure below). At the beginning of the melting process, both sample and furnace temperatures are identical; the furnace and sample temperatures are thermally equilibrated beforehand. the stamford grand adelaide
