The behavior of the sample that was cooled and then remolded should be explained. Concept introduction: The melting point of a crystalline substance is the temperature at which the substance starts changes into the liquid phase. Melting point is directly associated with the presence of intermolecular forces like hydrogen bonding, dipole-dipole interactions. High molecular symmetry, large surface area, polarity is associated with high melting points. A pure compound melt at a narrow range and compounds with impurities have a wide range of melting points. Melting points are determined by filling the organic compound into the capillary tube with one end sealed.
