Vapor Pressure AP Chemistry Kit Glass Funnels_Filter Funnels providing the high-resistance leg ofRaoult?s Law can be proven empirically by measuring the change in vapor pressure as solute is added to a solvent. The measurements will be taken at different temperatures to demonstrate the effect of temperature on vapor pressure. 20 40 mesh size.
