9. True/False? a. At room temperature, H2 molecules have the same average kinetic energy as 02- b. The boiling point of a liquid is the temperature at which the vapor pressure and atmospheric pressure are the same. 10 marks c. Gas A diffuses 4 times as fast as gas B. Gas B must be 4 times as heavy as gas A. d. Liquid alcohol is placed in a container at 25C, which is sealed. The alcohol starts to evaporate and then stops because the pressure of the gas is the same as the vapor pressure of the liquid. e. f. Polar liquids would normally have higher heats of vaporization than non-polar liquids. Attractive forces between solute and solvent molecules are an important factor in solution formation
