That permanent dipole is able to … WebEvaporative Cooling: As water evaporates off the surface of an object, the faster moving molecules, with more kinetic energy, escape as a gas, while the lower energy molecules, with less kinetic energy, remain as liquid. This lowers the temperature on the surface from which the liquid is evaporating. Sweating is a form of evaporative cooling.

Web2 mrt. 2024 · Methanol, CH3OH, is a good solvent for polar substances because: (1) Methanol undergoes dipole-dipole interactions. (2) Methanol is able to form hydrogen bonds with the polar substances. (3) There are weak ion-dipole interactions in methanol. (4) The van der Waals forces in methanol cause repulsion. WebThe only attractive forces among the hexane and water molecules are London forces. Thus, a few hexane molecules will enter the water layer, but the strong attractive forces among the water molecules keeps most of the hexane molecules out. Similarly, a few water molecules will enter the hexane layer because of the water-hexane London forces. easington farm shop opening timesWeb27 apr. 2024 · Why hexane is a liquid?
