How does surface area affect boiling point
WebOctane will have a higher boiling point than 2,2,3,3‑tetramethylbutane, because it branches less than 2,2,3,3‑tetramethylbutane, and therefore has a larger “surface area” and more van der Waals forces. Note: The actual boiling points are nonane, 150.8°C octane, 125.7°C 2,2,3,3‑tetramethylbutane, 106.5°C Contributors and Attributions WebSurface area occupied by the liquid: Since evaporation is a surface phenomenon, the greater the surface area occupied by the liquid, the quicker it undergoes evaporation. Humidity of the surroundings: The greater the humidity of the atmosphere surrounding the water, the slower the rate of evaporation.

WebSep 7, 2024 · Why pressure affects boiling point? Pressure affects the boiling point of a liquid because it causes the pressure to increase within the liquid. The higher the pressure, the higher the temperature at which water will start to boil. This is because when water reaches its boiling point, the vapor pressure of water is equal to atmospheric pressure. 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

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. WebIncreasing the surface area of the solid increases the chances of collision taking place. Imagine a reaction between magnesium metal and a dilute acid like hydrochloric acid. The reaction involves collision between …
WebWhen he's looking at the -OH bonds for each molecule, he's imagining other molecules of the same chemical in close proximity engaging in hydrogen bonding thus creating stronger attractions between the molecules which affects their boiling points. This is also why he investigates their London dispersion forces which is weaker intermolecular force. WebFeb 15, 2000 · Posted by Pam Young. Grade level: 4-6 School: Marine City Middle School.

WebThe shape of a molecule can also affect the boiling point. Typically, molecules with a smaller surface area have weaker London forces and result in lower boiling point.
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. ipad air 2 rugged case hand strapWebFeb 8, 2024 · How does surface area affect boiling point?
