WebFeb 20, 2016 · When a liquid evaporates in the open, the condensation rate is negligible. Increasing the surface area increases the evaporation rate, but it has little effect on the condensation rate. Hence, water in an open dish evaporates faster than water in a test tube, but the vapour pressure does not change. Answer link

WebMay 31, 2014 · The strength of Van der Waals forces depends primarily on the number of electrons in total in the molecule, so larger molecules will have higher boiling points. For isoelectonic molecules (isomers with the same number of electrons) what determines the strength of the Van der Waals forces is the area of surface contact. WebApr 9, 2024 · As the branching is done in a molecule or the branches increase the surface area of the molecule decreases which results in the decrease of van der waals attraction. Due to decrease in attraction it becomes easier to overcome a molecule, at low temperature we can overcome it, hence the boiling point of an alkane decreases on branching.
