CHM 115 Chapter Notes - Chapter 1: Cookie Dough, Maple Syrup, Human Eye
Document Summary
Chemistry: the study of composition, properties, and interactions of matter. Chemistry also occurs whenever someone is involved in changes in matter or in conditions that may lead to such changes. Hypothesis: a tentative explanation of observations that acts as a guide for gathering and checking information. Law: summarizes a vast number of experimental observations, and describe or predict some facet of the natural world. Theory: a well-substantiated, comprehensive, testable explanations of particular aspects of nature. Macroscopic domain: the realm of everyday things that are large enough to be sensed directly by human sight or touch. Microscopic domain: the realm of atoms and molecules- mostly too small to be seen with even a microscope. Symbolic domain: contains the specialized language used to represent components of the macro and microscopic domains. One of the features that makes chemistry so fascinating is the use of a domain that must be imagined to explain behavior in a domain that can be observed.
