Document Summary
Natural laws: concise statements, often in mathematical form , about natural phenomena (copernicus" law of earth) Depends on ability to explain/account for observations and to predict new phenomena. Hypothesis: tentative explanation of a natural law, if survives testing by experiments, becomes theory. Theory: model/way of looking at nature that can be used to explain natural laws and make further predictions about natural phenomena the less assumptions the better. Scientific method: combination of observation, experimentation, formulation of laws, hypotheses, and theories look at chem 120 notes pg. 2. Matter: anything that occupies space and displays the properties of mass and inertia. Even gases are matter, occupy space and have mass sunlight isn"t, it"s a form of energy. Composition: parts or components of a sample of matter and their relative proportions. Water = hydrogen 11. 9% and oxygen 88. 81% Properties: qualities or attributes that we can use to distinguish one sample of matter from others.
