2.11: Intermolecular Forces and Relative Boiling Points (bp)

Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP. WebBoiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases. An example of this would be the addition of ... 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 how to samsung edge 7 dictate text
