1. Review Matter

2. Behaviors of liquids and gases
Boyle’s principle- as the volume of gas decreases, the pressure of a gas increases, provided the temperature does not change. Ex: weather balloon

5. Recap question
Boyles principle as volume of a gas decreases the pressure __increase_______?

6. Recap question
Boyle’s law as volume of a gas increase pressure of the gas ____decrases___?

7. Behaviors of liquids and gases
Pascal principle – pressure applied to a fluid is transmitted unchanged throughout the fluid. ex: squeezing the end of a tube of toothpaste.

9. Lets take a look
Egg in a plastic bag test.

10. Recap question
The pressure applied to a fluid stays the same through out the fluid is expressed by what principle? pascals

11. Behaviors of liquids and gases
Charle’s principle- as temperature increase, the volume increases, provided pressure remains constant. Ex: hot air balloon

13. Recap question
When temperature increase volume ___increases

14. Recap question
When temperature decrease volume ____? decrease

15. Behaviors of liquids and gases
Bernouilli’s principle- as the velocity of a fluid increases, the pressure exerted by the fluid decreases. Ex: the design of an airplane wing

17. Recap question
When velocity increases in a fluid then pressure ___ decreases?

18. Recap question
When velocity in a fluid decreases then pressure in the fluid increase>

19. Composition of matter
Compound- atoms of two or more elements combined. Ex: water, (H2O), carbon dioxide (CO2)

20. Composition of matter
Heterogeneous Mixture- mixture in which different materials can be easily distinguished. Ex: pizza and fruit salad

21. Composition of matter
Homogeneous- mixture in which two or more substances are uniformly spread out Ex: vinegar, salt water, Kool-Aid

23. Recap question
Italian dressing is an example of what suspsension colloid or a solution?

24. Recap question
Water is an example of what colloid, suspension, solution?
