The Proctor compaction test determines the relationship between maximum compactability andoptimum bulk density and this quantity. The plasticity value of soil is the difference between the twovalues of this quantity at the Atterberg limits. The Fischer titration is a standard technique used tomeasure this quantity in substances. One instrument used to measure this quantity can incorporatestrands of hair, and a subtype of that instrument is the (*) psychrometer. This quantity can be measuredusing the mass of a sample and an oven, and in the air, this quantity is measured by a hygrometer. For 10points, absolute humidity is measured in terms of a unit volume of air and this quantity.
