Gas Behavior at Standard Conditions

• To better understand gas behavior, a set of standard  conditions is used for comparing gas parameters.

17

• The values, 0ƒC (273.15 K) and 1 atm (760 torr) are  designated as standard temperature and pressure (STP):

• Under these conditions, the volume of one mole of an  ideal gas is 22.414 L, which is called the  standard molar volume:

• Most simple real gases have a standard molar volume  close to 22.4 L.
