Solids, Liquids,

and Gases


3

Solids

A solid has a definite shape and volume.

© V. Rauch (Scipi), 2009

4

Particles in a SolidThey are packed very tightly together.

I can’t move. I’m stuck here.Move over

Homer and hold still!


5

Types of Solids Crystalline Solids – These particles form

regular repeating patterns.


6

Examples of Crystalline Solids

Salt

Sugar

Quartz – different kinds of rocks


7

Amorphous Solids Particles are not in a regular pattern.


8

Examples of Amorphous Solids

Plastics – able to be molded Rubber- able to bounceGlass - flows


9

Liquids

A liquid has no shape of its own. It takes the shape of the container. Without a container, it will puddle. A liquid will change its shape but not its

volume.


10

Particles in a Liquid

Particles are free to move about. As a result, a liquid has no definite shape.


11

Viscosity

The resistance of a liquid to moving or flowing.

The slower a liquid moves the HIGHER its viscosity. It is thicker.


12

Examples of Fluids With Different Viscosities

Milk – LowGasoline – LowOil – MediumPancake Syrup – HighMolasses – HighLava – High


13

Gases Change volume very quickly and easily. Gas particles will spread out to fill a

container…

OR

Will squeeze together to fill the container.


14

Gas Particles

Spread apart filling all the space available to them.

Gas has no definite volume or shape.



Check Point

1) What are two characteristics of a solid?

2) What is viscosity? Give two examples of fluids – one with a low viscosity and one with a high viscosity.

3) How is a crystalline solid different from an amorphous solid?

4) List the four characteristics of a liquid.


If you would like another power point about gases, check out The Behavior of Gases at:

http://www.teacherspayteachers.com/Product/Behavior-of-Gases-Science-Power-Point

This ten slide power point is an introduction to the behavior of gases. It not only introduces and defines volume and pressure but it also illustrates why and how molecules speed up or slow down. Pictures, animation, and words are used to reach the different types of learners you might have in your classroom. The power point ends with a five question review quiz for the students.

This power point may be revised or edited to meet your classroom needs.
