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 VS of the pure sample equals the volume V of the system, VS = V. For sample s in a mixture, the ratio Vs·V-1 is the nondimensional volume fraction Φs of sample s. Quantities divided by volume are concentrations of sample s in a mixture, such as count concentration CX = NX·V-1 [x·L-1], and amount of substance concentration CB = nB·V-1 [mol·L-1]. Mass concentration is density ρs = ms·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.
