Melting point and boiling point graph
Web1 jun. 2024 · To build Model 2, we have analyzed melting points of 1500 molecules, which are listed in Table S2 in the Supporting Information. Recently, it was shown that square of molar mass is directly proportional to the melting point of n-alkanes [58].Indeed, the molar or molecular mass should be related to the melting point, but only indirectly as a … WebEstimate Boiling Point and Vapor Pressure. Use the interactive controls above to simplify calculations and improve the efficiency of your distillation or evaporation requirements. Our Pressure-Temperature Nomograph tool is an application of the Clausius-Clapeyron equation, which assumes the heat of vaporization is a constant over a pressure range.
