WebMay 24, 2024 · Melting (Solid → Liquid): The process of change of solid substance into its liquid state is called melting or fusion. The constant temperature at which the solid becomes liquid upon absorption of heat at constant pressure is called the melting point of that solid at that pressure. Generally melting point increases with the increase in pressure. http://butane.chem.uiuc.edu/pshapley/GenChem1/L21/2.html
