WebJan 16, 2024 · The isothermal compressibility is defined by the fractional differential change in volume due to a change in pressure. (4.3.1) κ T ≡ − 1 V ( ∂ V ∂ p) T. The negative sign is important in order to keep the value of κ T positive, since an increase in pressure will lead to a decrease in volume.

The isothermal compressibility is generally related to the isentropic (or adiabatic) compressibility by a few relations: where γ is the heat capacity ratio, α is the volumetric coefficient of thermal expansion, ρ = N/V is the particle density, and is the thermal pressure coefficient. In an extensive thermodynamic system, the application of statistical mechanics shows that the is… Web1. Gases C, E, and F. 3. The gas behavior most like an ideal gas will occur under the conditions in (b). Molecules have high speeds and move through greater distances between collision; they also have shorter contact times and interactions are less likely. Deviations occur with the conditions described in (a) and (c).
WebThe compressibility factor for an ideal gas is unity, which is typically written as Z = PV / RT. Do not mistake it with the isothermal compressibility coefficient. In the majority of engineering activities, the compressibility factor is used as a correction factor for optimal behavior. Suggest Corrections. 6.
