Web[1 mark C] Surface tension is the elastic property of a liquids surface, determined by its intermolecular forces, that allows it to resist an external force. Capillary action is the phenomenon in which liquids rise up into a narrow tube called a capillary. to get to an ethanol. Direct link to Richard's post Here's KA's video on dipo, Posted 10 months ago. The more water that evaporates from your skin, the cooler your skin feels. Substances with strong intermolecular forces will have a higher boiling point than substances with weaker intermolecular forces. Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly than are propane molecules. Asked for: formation of hydrogen bonds and structure. Does isopropyl alcohol evaporate faster than ethyl alcohol? Write the structures of the products of the following reactions : Answer: (i) The acidic hydration of propene gives propan-2-ol (isopropyl alcohol) (ii) NaBH 4 is a weak reducing agent. Legal. could view as a measure of the average kinetic this will keep happening where things go from liquid, https://www.khanacademy.org/science/ap-chemistry-beta/x2eef969c74e0d802:intermolecular-forces-and-properties/x2eef969c74e0d802:intermolecular-forces/v/dipole-dipole-forces. To describe the intermolecular forces in liquids. So I will leave you there. The strength of the intermolecular forces in isopropyl alcohol are in between water and acetone, but probably closer to acetone because the water took much longer to evaporate. Changes from a more-ordered state to a less-ordered state (such as a liquid to a gas) are endothermic. of Evaporation | A Lab Investigation What Are the Intermolecular Forces of Isopropyl Alcohol?
