Matter is defined as anything that occupies space and has mass, and it is all around us. Define and give examples of atoms and molecules.Classify matter as an element, compound, homogeneous mixture, or heterogeneous mixture with regard to its physical state and composition.Apply the law of conservation of matter.
Describe the basic properties of each physical state of matter: solid, liquid, and gas.By the end of this section, you will be able to:
