WebSep 7, 2024 · When there is conversion of solid state to a liquid state at a specific point then that point is known as melting point. When the atmospheric pressure equals the vapour pressure of the liquid that temperature point is known as boiling point. This is basically used for solid state compounds, or molecules. WebThe melting point is the temperature at which a substance changes state from solid to liquid at atmospheric pressure. When considered as the temperature of the reverse change (from liquid to solid), it is referred to as the freezing point. Choose Elements to Display.
