Gases, Liquids, Solids 1. Properties of Liquids Compare the polarity of liquids with four properties of gases; 1. Gases can be compressed; liquids cannot 2. Gases expand to fill their containers; liquids do not 3. Gases have low densities; liquids have relatively high densities 4. Gases can be mixed in a fixed volume; liquids cannot Properties of Liquids and Intermolecular Attractions (IMA); 1. Vapor pressure : liquids w/relatively strong IMA evaporates less readily 2. Molar heat evaporation : the energy required to change one mole of a liquid to a gas 3. Boiling point : liquids w/strong IMA require higher temp. for boiling. Liquid boils when vapor pressure is slightly greater than the pressure above it. The temperature at which this occurs is the boiling point. At a given temperature liquids exert a pressure called vapor pressure 1 Atmospheric = Vapor Pressure = Boiling ( temperature = kinetic energy of molecules) boiling is dependent upon atmospheric pressure
