PROPERTIES OF LIQUID

• FLUID - A liquid or gas; a substance that flows
• SURFACE TENSION - It is the elastic force in the surface of a liquid.
• CAPILLARY ACTION - It is the tendency of a liquid to rise in narrow tubes or to be drawn into small openings.
• VISCOSITY - A measure of a fluid’s resistance to flow.
• VAPOR - A gaseous substance that exists naturally as a solid or liquid at normal temperature.
• VAPORIZATION - The change of phase from liquid to gas/vapor.
• VAPOR PRESSURE OF A LIQUID - The pressure exerted by the vapor above the surface of the liquid in a closed container.
• BOILING POINT - The temperature at which a liquid boils. Normal boiling point is boiling point of a liquid when the external pressure is 1 atm.
• MOLAR HEAT OF VAPORIZATION - The amount of energy (usually in kilojoules) required to vaporize 1 mole of a liquid at a specific temperature.
• Cohesion - is the intermolecular attraction between similar molecules.
• Adhesion - is an attraction between unlike molecules, such as those in water and in the sides of a glass tube.
