Define viscosity, polymers, calorific value and steam emulsion number
Answers
Answer:
Explanation:
Viscosity is another type of bulk property defined as a liquid's resistance to flow. When the intermolecular forces of attraction are strong within a liquid, there is a larger viscosity
A polymer is a large molecule made up of chains or rings of linked repeating subunits, which are called monomers. Polymers usually have high melting and boiling points. ... The word polymer comes from the Greek prefix poly-, which means "many", and the suffix -mer, which means "parts.
Calorific value is the heat produced by a given weight of fuel on the completion of combustion; it is measured in kilojoules per kilogram (kJ/kg).
Steam emulsification number is the time (in seconds ) required for an emulsion of lubricating oil and water to separate into distinct layers at 900C.
Emulsification is the properly of oil to get mixed with water forming a dispersed phase of oil in water or water in oil, the emulsification property of oils is expressed in terms of stream emulsification number and is determined by A.S.T.M ( American society for testing material) method.
