The statements in the following multiple choices deal with various aspects of the relationship between vapor pressure and intermolecular forces. Choose the statement which is true. a) At a given temperature liquid O2 has higher vapor pressure than liquid H2. b) The more surface area water has the higher the vapor pressure it develops. c) The average kinetic energy of boiling water molecules is the same on a mountaintop as it is at sea level. d) Liquids have lower vapor pressures at high temperatures than they do at lower temperatures. e) A pressure cooker works by increasing the vapor pressure water has to reach in order to boil
