111. What is a chemical reaction?
It is a chemical change in which elements combine to form compounds or breaking out compounds to recombine to form new compounds.
112. What is exothermic reaction? What is Endothermic reaction?
A chemical reaction in which heat is liberated is called exothermic reaction
Example: union fining reaction
A chemical reaction in which heat is absorbed is call endothermic reaction
Example: pacol reaction
113. What is DPK? Where Return kerosene is used?
DPK: Duel purpose kerosene. Return kerosene used as Jet A, B, JP & JPB)
114. What is paraffin?
Carbon atoms connected in a straight chain by single bond (normal) Butane C-C-C-C
115. What are iso paraffins?
Carbon atoms having branched chain, single bond arrangement is called Iso-parafins (non-normals).
Iso-butane C- C - C
