Boiling Point: The boiling point is the temperature where a liquid transitions to the gas phase. Boiling point can be influenced by the intermolecular forces of the substance. Mar 15, 2019 · Melting Point Definition. The melting point of any given substance is the temperature at which the substance experiences melting, or the moment that the substance changes from a solid into a liquid. Some materials, like metals, glass, and other substances which are solid at room temperature have a high melting point.
