5. Matter and its Characteristics Matter is anything that has mass and takes up space. Mass is a measurement that reflects the amount of matter. Weight is a measure of mass and the force of gravity on an object. Weight can change from place to place, but mass is constant. Much of matter and its behavior is macroscopic, meaning that it can be observed without a microscope. The structure, composition, and behavior of all matter can be described on the submicroscopic (atomic) level. Chemistry explains events on the atomic level (submicroscopic) that cause macroscopic observations. A model is a verbal, visual, or mathematical explanation of experimental data.

6. Chemistry: The Central Science A basic understanding of chemistry is central to all sciences—biology, physics, Earth science, ecology, and others. Chemistry is traditionally broken into branches that focus on specific areas such as: Organic chemistry Inorganic chemistry Physical chemistry Analytical chemistry Biochemistry Environmental chemistry Chemistry and Matter Copyright © McGraw-Hill Education Industrial chemistry Polymer chemistry Theoretical chemistry Thermochemistry
