For 10 points, identify this quantity, the pressure of a gas in equilibrium.
A Knudsen cell can be employed to measure low values of this quantity in solids. This quantity, which can be measured using an isoteniscope, is higher than normal for a convex-curved droplet. Two substances with equal values for this quantity are linearly related with respect to their temperature on a Duhring plot. The log of this quantity can be set equal to "A minus B over C plus T" in (*) Antoine's equation. Substances with higher values of it are considered more volatile. This quantity's "partial" form is calculated by multiplying it with a mole fraction value in Raoult's law. A sample reaches its boiling point when this quantity equals the atmospheric pressure. For 10 points, identify this quantity, the pressure of a gas in equilibrium.
