3. Chemical Change a change in which a substance becomes another substance having different properties a change that is not reversible using ordinary physical means Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes You usually need more than one of the above characteristics to be considered a chemical change! Examples combining sulfuric acid and sugar burning a piece of wood soured milk

4. Chemical or Physical Change? 1.Bending a Paper Clip 2.Baking a cake 3.The sublimation of carbon dioxide 4.Crushing an aluminum can 5.Vinegar and baking soda combining to create salt and water Physical Change Chemical Change Physical Change

5. Mass vs. Weight Mass a measure of how much matter an object is made of does not change, regardless of where something or someone is Weight the force of gravity on an object equal to the mass of the body times the local acceleration of gravity http://www.exploratorium.edu/ronh/weight/index.html Why do you think the person’s weight is less on the moon? Mass = 59 kg Weight = 579 N Weight = 96 N

6. 5 Physical States of Matter Bose-Einstein Solid Liquid Gas Plasma (Newest State)

7. Bose-Einstein Condensate Exist at extremely cold temperatures (around absolute zero or -460 o F) Particles are super unexcited Particles lock or “ clump ” together so firmly that they move as a single unit Definite shape and volume (?)

8. Solid Particles are tightly compact Particles vibrate without the ability to move freely Definite shape and volume Solid Animation

9. Liquid Particles are tightly compact, but able to move around close to each other No definite shape, but definite volume Liquid Animation

10. Gas Particles can easily spread out or move close together Particle move freely and with a lot of energy No definite shape or volume Gas Simulation

11. Plasma Exist at extremely high temperatures (several million degrees Celsius) Particles are broken apart Particles move freely and with extremely high energy This form is not too common on Earth, however it is the most common form of matter in the universe No definite shape or volume (?) Examples: Florescent and neon lights, lightning, aurora borealisaurora borealis - - - Why do you think this is the most common form/state of matter in the universe? + + +

12. Energy and the States of Matter The physical states of matter result from the amount of energy the particles composing the matter have. Basically, more energy means more movement for the particles and less energy means less movement. Energy/Temperature and Matter Simulations –PhETPhET –BEC: Temperature and Absolute ZeroBEC: Temperature and Absolute Zero If you were to compare an ice cube and the steam created from boiling water, which would you think has more energy?

13. States of Matter Continuum Taken from: http://www.chem4kids.com/files/matter_becondensate.htmlhttp://www.chem4kids.com/files/matter_becondensate.html What about this continuum could be considered a little misleading?

21. Density a measure of the amount of matter present in a given volume of a substance typically expressed in the following units: –grams per cubic centimeter (g/cm 3 ) for solids –grams per milliliter (g/ml) for liquids does not depend on how much of a substance you have (intrinsic property) – in other words, the density of a gold bar would be the same as the density of a gold flake can change as temperature and pressure change Which do you think is more dense? Why?

22. Layering Liquids Using a test-tube and the eyedroppers, try to layer the four different colored liquids so that the colors don’t mix and show distinct layers. 1.Hold the test-tube in your hand at a 45 degree angle. 2.Using the eyedropper from one of the colors, slowly place the liquid into the test-tube. 3.Repeat step two using the other three liquids until you get them layered. Record the order of the colors. If you don’t get clear separation of the colors, you should empty the contents of the test tube down the drain and start again. These steps may need to be repeated several times until you discover the correct order of the colors. *Placing white paper behind the straws will help you see the divisions

23. Layering Liquids - Discussion 1.Were you capable of layering the four liquids? If so, what was the correct order from the bottom up? 2.What difficulties did you experience when performing this activity? 3.Why do you think the liquids created layers when putting them in the test tube in the correct order? 4.Because these liquids are miscible, or partially miscible, they did not really create distinct layers. What do you think it means to be miscible?

26. Calculating Density Density can be calculated by dividing the mass of an object by its volume D = m V Sample Problem Timothy found a solid metal block that has a mass of 100 grams and a volume of 25 cm 3. What would be the density of the block? D = = 100 grams 25 cm 3 4 grams cm 3

27. Practice Problems 1.Find the density of a substance with a mass of 27 g and a volume of 7 cm 3. 2. A block of maple has a mass of 20 grams and a volume of 26.5 cm 3. What is the density of the block? D = m V D = m V D = = 27 g 7 cm 3 3.86 grams cm 3 D = 20 grams 26.5 cm 3 = 0.75 grams cm 3

28. The Density Triangle DV m. D = m V V = m D m = D V.

30. Mixture Notes

31. Solvent Part of the solution that is present in largest amount and dissolves a solute What liquid is called the “ universal solvent ” ? Solvent - Solute - Solution WATER

32. Solute Part of solution present in lesser amount and dissolved by solvent

33. Solution A well mixed mixture containing a solvent and at least one solute that has the same properties throughout.

34. Properties of Matter –

35. Physical Property Characteristic of a pure substance that can be observed WITHOUT changing it into another substance.

36. Chemical Property A characteristic of a pure substance that describes its ability to change into a DIFFERENT substance.

37. Mixture Made of two or more substances- elements, compounds or both- that are together in the same place but are not chemically combined.

38. Heterogeneous Mixture You can see the different parts

39. Homogeneous Mixture So evenly mixed that you can ’ t see the different parts
