Answer to Question #101469 in General Chemistry for Ashish

Question

What is relative lowering of vapor pressure? How can lowering of vapour pressure be
measured using static method?

Answer 1

Vapor pressure is defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. The static method for measuring vapor pressure assumes that the sample is pure and that its temperature is steady and uniform.
