WebMay 21, 2016 · The longer the alkyl chain, the greater the degree of dispersion force between molecules, and thus the greater the boiling point. Of course, as a chemist, as a physical scientist, you should look up the boiling point of the straight chain alkanes. WebTemperature is not directly proportional to internal energy since temperature measures only the kinetic energy part of the ... is 0.01K below that at 273.15 K. If you want to be really precise about it, the boiling point is 373.125 K, or 99.975 °C relative to the standard pressure freezing point. But for general purposes, just 0 °C and 100 ...
