Given the following vapor pressure of volatile compounds at 25C, ethyl alcohol is more volatile than diethyl ether. diethyl ether =520 torr ethyl alcohol =75 torr True False Question 7 The vapor pressure increases as the temperature increases. The heat energy increases the kinetic energy of moving liquid particles, hence permitting the molecule to escape from the liquid phase. The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure. True False
