Viscosity is resistance to flow Liquids that flow slowly and are hard to stir or pour have a high viscosity Liquids that flow easily and quickly have a low viscosity For example honey has a high viscosity and water has a low viscosity Viscosity also controls how fast objects move through liquids the higher the viscosity the harder it is for objects to push through the liquid Surface tension is resistance to penetration of a surface or any increase in surface area Fluids that form more compact rounder drops on surfaces or which more strongly resist penetration by small objects have a high surface tension Vapor pressure is how quickly and completely a liquid evaporates Liquids with a high vapor pressure evaporate quickly and when in a closed container produce a higher partial pressure of vapor at equilibrium All three of these properties are the result of intermolecular forces between the atoms or molecules that make up the liquid In this case both drops have the same curvature so the surface tension of the two liquids must be the same However the drop of Liquid X is evaporating faster because it gets smaller faster That means Liquid X has a higher vapor pressure Liquid Y EO ANSWER vapor pressure
