When heat is supplied to bottom of liquid stage to vaporize a portion

1.	When heat is supplied to bottom of liquid stage to vaporize a portion it is called(a) Condensing(b) Boil up(c) Cooling(d) DesaltingI had been asked this question in a national level competition.The question is from Theoretical Stages topic in portion Key Fractionation Concepts of Distillation Design
Answer» Correct ANSWER is (B) BOIL up To elaborate: Such operations USED in stripping section called as Boil up, the boiler is used as a heat exchanger to reheat the condensed liquid.
