Q. What do you eman by Scientific Research?
Pure research is prepared to gain knowledge for the sake of knowledge itself. Molina as well as Rowland's research on the behavior of CFCs- showing that in the lab CFCs could speed up the breakdown of ozone-was motivated by their curiosity and is an instance of pure research. Applied research is carrying out to solve a specific problem. Scientists are conducting experimentation to find chemicals to replace CFCs. These experiments are instance of applied research.
