Properties of Liquids Viscosity Properties of Liquids Viscosity - it is the liquid’s resistance to flow. - refers to the thickness of the liquid.  Properties of Liquids Viscosity High viscosity and low viscosity Viscosity Viscosity Viscometer - it is the device use to measure the viscosity of a liquid Surface Tension Properties of Liquids Surface Tension - the energy required to increase the surface area of a liquid - it is the tendency of liquids to minimize their surface area Properties of Liquids Surface Tension - The tendency of a liquid surfaces at rest to shrink into the minimum surface area possible - It is the force that causes the liquid to contract. Surface Tension Surface Tension Surface Tension Surface Tension Adhesion Cohesion Adhesion and Cohesion Adhesion and Cohesion Adhesion and Cohesion Adhesion and Cohesion Adhesion and Cohesion Capillarity  Properties of Liquids Capillarity - a.k.a. Capillary Action - It is the spontaneous rising of a liquid in a narrow tube.  Capillarity This is the movement of liquids against gravity Capillarity Capillarity Capillarity Capillarity  Vapor Pressure  Properties of Liquids Vapor Pressure - is the equilibrium pressure of a vapor/ gas phase above its liquid (or solid). - is the pressure exerted by vapor equilibrium with its liquid in a closed container. Vapor Pressure Evaporation Boiling Vaporization - a broader term that includes evaporation and boiling.  Vaporization Evaporation Boiling - occurs on the - occurs on the surface of the entirety the liquid. liquid.  Properties of Liquids Boiling Point - is the temperature wherein the vapor pressure is equal to the external pressure. Boiling Point  Heat of Vaporization  Properties of Liquids Heat of Vaporization - a.k.a. Enthalpy of Vaporization, it is the amount of heat energy to change/ convert a given amount of liquid into gas. Heat of Vaporization Substance Molar Heat of Vaporization (kJ/mol) Water 40.79 Ethanol 38.56 Acetone 31.3 Ethyl Ether 26.8 Benzene 30.8
