: Vapor pressure is defined as the force applied on the compartment walls by the vapour .Also , it can be the force applied by the wall on the liquid to prevent it from more evaporation .In this experiment Reid method will be applied to measure the vapour pressure of gasoline.Measuring vapour pressure is essential in order to find the appropriate container size and storing temperature to prevent accidents or explosions from occurring and to insure safety during operation hours. Experimental Results : Table #1 :Pressure measurement at different times for gasoline at 100

Conclusion : In this experiment,we were able to calculate vapour pressure of gasoline by applying Reid method .P* was found to be ( 7.2 lb/sq.in )at 100 o F....
