Solids
Gases Liquids

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.
