    Comment "If the changes are of a strictly physical nature (for example, mixing, distillation, drying, filtration, adsorption, condensation), the step is referred to as a unit operation. If the changes are of a chemical nature, where conversion from one chemical species to another takes place (for example, combustion, polymerization, chlorination, fermentation, reduction, hydrolysis), the step is called a unit process. Some steps involve both, for example, gas absorption with an accompanying chemical reaction in the liquid phase. The term chemical conversion is used not only in describing overall processes involving chemical transformation, but in certain contexts as a synonym for the term unit process. The chemical process industry as a whole has tended to favor the former usage, while the petroleum industry has favored the latter.Reference: ""chemical conversion"".

    Comment "Une transformation chimique s'accompagne d'une modification des espèces chimiques présentes dans l'état initial. Les atomes présents dans les molécules de départ sont redistribués afin de former de nouvelles molécules.(Source: Site d'Assistance scolaire personnalisée > Collège> Physique-chimie > La transformation chimique, https://www.assistancescolaire.com/eleve/3e/physique-chimie/reviser-une-notion/la-transformation-chimique-3_pc_06 [15.12.2017])"
