Answer

Brief Explanations:

  1. Unit operations are the building - blocks of processes in chemical engineering and related fields. They are basic steps that can be combined to form complex processes.
  2. A pump creates pressure to move liquids. This is its fundamental function in fluid - handling systems.
  3. The role of a heat exchanger is to transfer heat between fluids. It is used in many industrial and domestic applications for heating or cooling purposes.
  4. A separator is used to divide mixtures into components based on differences in physical properties like density, boiling point etc.
  5. Chemical changes occur in reactors where chemical reactions take place. Since no option for reactor is given, and a separator is mainly for physical separation, there may be an error in the options for this question. But conceptually, a separator is not where chemical changes occur.

Answer:

  1. B. The building blocks of processes
  2. B. Creates pressure to move liquids
  3. B. Transfers heat between fluids
  4. C. Divide mixtures into components
  5. (No correct option given among A - D as chemical changes occur in reactors typically)
