state at atmospheric pressure This transition is characterized by a distinct plateau in the heating curve reflecting the absorption of latent heat of fusion the energy required to overcome intermolecular forces holding the solid structure together Think of it like breaking apart a tightly packed stack of blocks it takes energy to separate them Impurities disrupt this structured arrangement lowering the melting point and broadening the melting range A sharper narrower melting range therefore indicates higher purity The Role of Omega Engineerings Automatic Melting Point
