Intermolecular Forces and Vapor Pressure Multiple Choice 1 point Vapor Pressure is defined as the pressure exerted by a gas above the Vapor Pressure Graph liquid from which it evaporated after the rates of evaporation and condensation have equalized. The more molecules that escape to the vapor (gas) phase, the greater the vapor pressure. The graph of vapor pressure as a function of temperature shows how yaa a . the vapor pressures of different substances change as temperature Vapor pressure is inversely related to boiling point. increases. 34.6 C 78.3 C 800 (OU Pap ag E Normal boiling = ! point w 600 | Diethyl a Z ether Ethyl alcohol a (ethanol) = 400 B 200 Ethylene glycol 0 20 40 60 80 100 Temperature (C) Which substance graphed has the greatest vapor pressure ata temperature of 20C?
