Questions 1.What is distillation? 2.What is chemical reactor? 3.What is chemical process? 4.What is the main role of chemical engineers? 5.What is Viscosity? 6.What is volatility? 7.What is unit operation? Answers: 1.Distillation is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. 2.A chemical reactor is an enclosed volume in which a chemical reaction takes place. In chemical engineering, it is generally understood to be a process vessel used to carry out a chemical reaction 3.In a scientific sense, a chemical process is a method or means of somehow changing one or more chemicals or chemical compounds. Such a chemical process can occur by itself or be caused by an outside force, and involves a chemical reaction of some sort 4.The main role of chemical engineers is to design and troubleshoot processes for the production of chemicals, fuels, foods, pharmaceuticals etc 5.Viscosity is a measure of a fluid's resistance to flow. 6.In chemistry, volatility is a material quality which describes how readily a substance vaporizes 7.In chemical engineering and related fields, a unit operation is a basic step in a process. Unit operations involve a physical change or chemical transformation such as separation, crystallization, evaporation, filtration, polymerization, isomerization, and other reactions
