4. Basic research describes the desire to increase knowledge like the how and why a reaction occurred or the properties of a specific substance. An example is the serendipitous discovery of Teflon by Roy Plunkett; through basic research, the properties, structure, and composition were determined. Applied research refers to solving a problem that requires attention. This includes inventing new refrigerants that are more environmentally safe. Technological development involves the production and use of products that improve the quality of life. An example is the emergence of computers.
5. a) Mass is a measure of the amount of matter.
