Question
Chapter 9, Problem 9.2QAP
Interpretation Introduction
Interpretation:
An effect of absorption profile of three different elements is to be described as given in the figure. Like this absorption profile, other elements also need to be explained.
Concept introduction:
Absorption profile of elements is explained by the relationship of absorption and the height of flame. Effects of absorption profile of elements depend on the atomization efficiency of elements.
