CH 301 Study Guide - Midterm Guide: Metallic Bonding, Capillary Action, Surface Tension
Document Summary
Ch 301 lecture 19: solids, exam 3 review. Exam 3: 33 questions @ 3 pts each -> 99 pts. The stronger the imf, the bigger the property melting pt boiling pt viscosity surface tension capillary action. Very high melting points, more than 500 degrees celsius needed. Every solid state that is not a metal does not conduct (except graphite) When ions are free in liquid state, it conducts, either from dissolving or melting. Covalent solids ex: sugar relative low melting point. Metal solids (metallic bonding (a lot of delocalized orbitals aka conduction band)) conduct both in solid and liquid state melting point has a wide range ductile and malleable. Ch 301 lecture 19: solids, exam 3 review it is the resistance to ow of a liquid. Imfs are always important very important = shape (esp. long chains will entangle and increase viscosity) Surface molecules must overcome imfs to increase vapor pressure heat(deltahvap) + h2o (l) -> h2o (g) evaporation.
