Document Summary
Chapter 12 questions 1, 22, 29, 36, 41, 51, 65, 87, To use the ideas of intermolecular forces to: Understand the relation between temperature, pressure and state of matter. In gases we saw that the speed and kinetic energies of molecules vary, even at the same temperature. In a liquid, some molecules will always have sufficient kinetic energy to overcome intermolecular forces and escape into the gaseous state. Molecules can escape from the liquid into vapour. Gas phase molecules can condense into the liquid. An equilibrium is set up between evaporation and condensation. The result is that there is constant partial pressure of the vapour called the vapour pressure. Vapour pressure is usually determined by allowing a liquid to come into equilibrium with its vapour and using the ideal gas law to determine the equilibrium pressure.
