Volume

Description

Volume V is a derived quantity based on the SI base quantity length [m] and is expressed in terms of SI base units in the derived unit cubic meter [m³]. The liter [L = dm³] is a conventional unit of volume for concentration and is used for most solution chemical kinetics. The volume V contained in a system (experimental chamber) is separated from the environment by the system boundaries; this is called the volume of the system, and described in practical language as big/small (derived from length, height) or voluminous. Systems are defined at constant volume or constant pressure. For a pure sample S, the volume V_S of the pure sample equals the volume V of the system, V_S = V. For sample s in a mixture, the ratio V_s·V^-1 is the nondimensional volume fraction Φ_s of sample s. Quantities divided by volume are concentrations of sample s in a mixture, such as count concentration C_X = N_X·V^-1 [x·L^-1], and amount of substance concentration C_B = n_B·V^-1 [mol·L^-1]. Mass concentration is density ρ_s = m_s·V^-1 [kg·L^-1]. In closed compressible systems (with a gas phase), the concentration of the gas increases, when pressure-volume work is performed on the system.
