How does surface area affect boiling point
WebThe speed of air that is flowing across water will affect how quickly the water evaporates. The three main parameters that control the evaporation rate of a body of water are: the surface area, the temperature, and the partial pressure 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

WebMay 8, 2024 · $\begingroup$ Okay, so for the melting point, we have three different effects : 1) The molecule becomes more sphere-like, so the surface area decreases, and the strength of the Van Der Waals forces decrease. 2) The length of each chain becomes longer, so the Van Der Waals forces increase. 3)In general, branching decreases the symmetry of the … WebFeb 19, 2024 · Answer. 4 people found it helpful. penu2008. Branching decreases the boiling point. As the length of carbon chain increases, the surface area of the compound will also increase. Van der Waals dispersion force is proportional to the surface area. So the increase of surface area increases the ability of individual molecules to attract each other.
WebJul 21, 2024 · An increase in the surface area facilitates evaporation of the sweat by absorption of heat equal to the latent heat of vaporization from the body and the cotton clothes. As a result, our body feels cool & comfortable. Similarly, when we take ice-cold water in a glass tumbler, we see water droplets on the outer surface of the glass. WebNov 14, 2013 · The above extract from my book, mentions clearly that branching makes the molecule more compact and thereby decreases the surface area. Even for isomeric alkyl …
WebApr 16, 2024 · Increasing the contract surface area between hydrocarbons raises boiling point, so hexane should have a higher boiling point than propane. This doesn't really make sense to me. What is the difference between pulling apart a pair of propane twice, versus one pair of hexane? Why would the total amount of energy needed differ? The surface area of the molecule depends on the amount of Van Der Waal’s force acting between the molecules. The force of attraction increases with the increase in surfsce area. Due to strong attractive forces the boiling becomes difficult. If the carbon atoms make a compound using branches then it might … See more Boiling point is that value of temperature at which the vapour pressure of the liquid surface reaches the value of pressure of the surroundings. By increasing the temperature we are … See more The correct interpretation of this question is what is the effect of surface area on the boiling point of the mixture? We all must have known by now the effects of temperature and pressure on the boiling point. When the … See more We have already discussed this in above sections that the boiling point of the compound will increase if the chain has more carbon atoms attached in a linear fashion. It is … See more The relation between boiling point and surface area is already discussed in the above section. The boiling point increases as the surface area of the molecular compound increases. … See more
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.
