Document Summary

Chapter 11: liquid water and aqueous solutions, static fluids. Fluid = deformable so evolve toward mechanical eq"m in given space. Thermal energy of system dominates = gas uid. If in condensed liquid state, pascal"s law: pressure increase linearly with depth below surface (pressure at liquid surface = pressure in adjacent gas space) Surface of condensed ideal stationary uid has properties distinct from those of bulk material due to excess energy required to form surface (surface tension/energy), which causes pressure diff across bubble / droplet surface inversely proportional to radius. Model system: ideal stationary uid = systems that yield to any force that attempts to alter their shape, causing system to ow until reaches mechanical eq"m in which uid then conforms to shape of container. Liquids and gases, but not solids (don"t change shape for container) Liquids: molecules in condensed state, maintain constant intermolecular distance, forms surface in container of larger volume than liquid occupying volume.
