(p.54) Matter and Thermal Energy

Chapter 3:
3-1/ 3 States of Matter and characteristics of each
2 Types of Solids and characteristics of each
Which states of Matter can be described as fluid
Recall Surface Tension

3-2/Changes of State of Matter: Between Solid /Liquid, Between Liquid/Gas, Between Solid/Gas and how thermal energy, temperature, and particle motion cause these changes in state of matter

3-3/3 measurement helpful to know when working with gas.  Pressure = Force / Area

Introduction to Matter:

     Matter

Properties of Matter

Compounds (define)

Chemical formula

When elements chemically combined, they form compounds having properties that are different from those of the uncombined elements.

Mixtures (define)

Each substance in a mixture keeps it individualproperties

The parts of a mixture are not combined in a set ratio
