1 Matter Study Guide 2008

2 Anything that has a mass and a volume

3 Close up view of atoms and their behavior Animated images are from

4 4 States of Matter Solids Particles of solids are tightly packed, vibrating about a fixed position. Solids have a definite shape and a definite volume.

5 5 States of Matter Solids Particle Movement Examples

6 6 States of Matter Liquids Particles of liquids are tightly packed, but are far enough apart to slide over one another. Liquids have an indefinite shape and a definite volume.

7 7 States of Matter Liquids Particle Movement Examples

8 8 States of Matter Gases Particles of gases are very far apart and move freely. Gases have an indefinite shape and an indefinite volume.

9 9 Gases Particle Movement Examples States of Matter

10 10 States of Matter Plasma A plasma is an ionized gas. A plasma is a very good conductor of electricity and is affected by magnetic fields. Plasma, like gases have an indefinite shape and an indefinite volume.

11 11 States of Matter Plasma Particles The negatively charged electrons (yellow) are freely streaming through the positively charged ions (blue ).

12 12 States of Matter Plasma Examples

13 Changing from one state to another is a Physical Change. If a new substance is formed it is a Chemical Change. Images are from

14 The building blocks of Matter Consists of Protons (+), Electrons (-), and Neutrons (N). Images are from

15 Elements Consists of only one kind of atom, Cannot be broken down into a simpler type of matter by either physical or chemical means Can exist as either atoms or molecules.

16 A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together. In the animation above, two nitrogen atoms (N + N = N2) make one Nitrogen molecule.

17 Animated images and notes from Atoms of two or more different elements bound together. Can be separated into elements chemically, but not physically. In the animation above, water (H 2 0) is a compound made of Hydrogen and Oxygen. Compounds

18 They are substances held together by physical forces, not chemical. Can be separated physically. Solutions are also mixtures. The substances are not uniformly mixed. Example: Sand in a glass of water. Images are from

19 Solutions are groups of molecules that are mixed up in a completely even distribution. Uniform Distribution. Example: Sugar and Water Images are from

20 The substance to be dissolved. The one doing the dissolving. Images are from

21

22 Concentrated – strongConcentrated – strong examples; frozen orange juice in a can, laundry detergent, powdered milk, can of soda examples; frozen orange juice in a can, laundry detergent, powdered milk, can of soda Diluted – weakDiluted – weak examples; orange juice mixed in jug with water, powdered milk mixed with water, soda in melted ice examples; orange juice mixed in jug with water, powdered milk mixed with water, soda in melted ice Concentration of Solutions

23 Are heterogeneous mixtures consisting of parts that are visible to the naked eye. Example: the ingredients in salad dressing Substances will settle over time.

24 Particle sizes are in between the size of particles found in solutions and suspensions. Can be mixed and remain evenly distributed without settling out.
