1 Ch.1: Matter and Change 1.1 Chemistry

2 Sciences used to be divided into strict categories
physical (nonliving) biological (living) Chemistry has parts that fall under both categories many sciences are so interrelated that you can’t categorize them in those ways anymore.

3 Chemistry study of matter and the changes it undergoes
chemists use instruments to improve their ability to observe and make measurements

4 Chemistry chemists work with chemicals (any substance with definite composition) all matter has chemical basis whether it is living or nonliving

5 Branches of Chemistry organic- study of compounds containing carbon
inorganic- study of compounds that aren’t organic physical- study of changes of matter and their energy

6 Branches of Chemistry analytical- study of composition of materials
biochemistry- study of substances and processes in living things theoretical- use of math and computers to understand chemical behaviors and design new compounds

7 Types of Research Basic Research- done to increase knowledge
Applied Research- done to solve a problem Technological Development- done to improve quality of life technology – application of knowledge (usually scientific) for practical purposes

8 1.2 Matter and Its Properties
Ch. 1: Matter and Change 1.2 Matter and Its Properties

9 Terms Matter- anything that has mass and volume
Atom- smallest unit of an element that keeps the properties of element Element- pure substance made of only one type of atom Compound- substance made of 2 or more types of atoms that are chemically bonded Molecule- type of compound in which bonds are covalent bonds

10 Properties of Matter chemists use characteristic properties to tell substances apart and to separate them some properties define a group of substances

11 Types of Properties Extensive- depend on the amount of matter
Ex: volume, mass, amount of energy Intensive- do not depend on the amount Ex: density, boiling point, ability to conduct

12 Types of Properties Physical- characteristics that can be observed or measured without changing the identity of a substance Chemical- relates to a substances ability to undergo changes that transform it into a different substance Easiest to see when a chemical is reacting
