Study Notes
Properties of Liquids
- Liquids exhibit properties like surface tension, viscosity, vapor pressure, boiling point, and molar heat of vaporization.
- These properties are influenced by intermolecular forces (IMF).
- Stronger IMF lead to higher surface tension and viscosity, lower vapor pressure, and higher boiling points.
Surface Tension
- Surface tension is the energy required to increase a liquid's surface area.
- Liquids with stronger IMF have higher surface tension.
- Water's high surface tension is due to hydrogen bonding.
Cohesion and Adhesion
- Cohesion is the attraction between liquid molecules.
- Adhesion is the attraction between liquid molecules and other molecules.
- Capillary action results from the balance of cohesion and adhesion.
- Water's adhesion to glass is greater than its cohesion, leading to a concave meniscus.
- Mercury's cohesion is greater than its adhesion to glass, leading to a convex meniscus.
Viscosity
- Viscosity is a liquid's resistance to flow.
- Stronger IMF lead to higher viscosity; liquids flow more slowly.
- Higher temperatures decrease viscosity; molecules move more freely.
Vapor Pressure and Boiling Point
- Vapor pressure is the pressure exerted by gaseous molecules above a liquid.
- Weaker IMF lead to higher vapor pressure and lower boiling points.
- Boiling point is the temperature where vapor pressure equals atmospheric pressure.
- Molar heat of vaporization is the energy needed to change one mole of liquid to gas.
Water Properties
- Water is an excellent solvent for many ionic and molecular compounds due to its polarity.
- Water has a high specific heat capacity, meaning it can absorb a lot of heat with a small temperature change. This is due to hydrogen bonds.
- Solid water (ice) is less dense than liquid water because the hydrogen bonding creates an open structure with more space between molecules.
- Water's ability to rise in thin tubes (capillary action) is important for biological processes, like water transport in plants.
