Sömu ástæðu og öll önnur efni bráðna. Not only is heat required to raise the temperature of the solid to the melting point, but the melting itself requires heat; see also latent heat and heat of fusion. From a thermodynamics point of view, at the melting point the change in Gibbs free energy (G) of the Material is zero, because the enthalpy (H) and the entropy (S) of the material are increasing (H,S > 0). Melting phenomenon happens when the Gibbs free energy of the liquid becomes lower than...
