This document defines and provides examples of solids, liquids, and gases. It discusses the particle structure and properties of each state of matter. Solids maintain a definite shape and volume, with particles that are close together and vibrate. Crystalline solids have repeating patterns that melt at distinct temperatures, while amorphous solids soften and then change appearance when heated. Liquids have volume but not a definite shape, with particles that are semi-close and can move. Gases have no definite shape or volume, with particles that are far apart and fill their container.

2. Table Of Content
• Introduction
• Define Solid, Liquid, Gas
• Examples of Solid, Liquid, Gas
• Assessing Your Understanding
• Resources

3. Solids form a shape and has a
volume

4. particles in solid
• are extremely close
• movement is possible
• it vibrates or slides back and forth

5. crystalline solids
• repeating patterns-made out of crystals which
are called crystalline solids
• things we see or use daily such as snow, salt,
and sugar are examples of crystalline solids
• however, if heat is applied to crystalline solids it
will melt at a distinct temperature

6. amorphous solids
• are not a regular pattern
• will not melt at a distant temperature
• materials become soft and then they
change appearances

7. • things we use and see that are
amorphous solids are rubber,
plastics, and glass
• heated glass will bend

8. Liquids have volume but do not
form a shape.

9. particles in liquids
• particles are semi-close
• they can move

10. surface tension
• a pull or force in liquids which causes the
molecules on the surface to become
closer together
• If water was dropped on a leaf it would
bead up and pull slightly together because
water molecules attract each other

11. viscosity
• a fluid that resist the force tending to
cause the fluid to flow
• liquids with a high viscosity flow more
slower (ex. honey)
• liquids with a low viscosity flow more
quicker (ex. vinegar and water)

12. Gas do not form a shape or
volume.

13. Particles in Gas
• is considered a fluid
• does have pressure
• separate as it moves

14. volume
• the amount of space that matter fills
• particles move and fill all available space
• value of gas is the same as the volume of its
container

15. Helium inside a container is
compressed or pressed together
tightly to fit into a metal tank. If
balloons are blown up with this helium
it expands to fill them making the
volume greater than the volume in the
tank

16. pressure
• The force of an outward push
• An object being filled comes from the
pressure of the gas

17. temperature
• Moves faster with hot gas particles
• Moves slower with cool gas particles

18. Assess Your Understanding
• Describe the two kinds of solids.
• Give an example of crystalline solid.
• Heat applied to this solid causes it to do
what.
• Liquids have volume but do not form this.
• Name a liquid that flow slowly.

19. cont. assess your understanding
• Describe one way gas may move.
• Hot gas particles causes temperature to
move how.
• The pressure of gas is the force of its what
type of push.
