What is matter?
Anything that has mass and takes up space
State whether each of the following is matter (M) or not (X): air ___, light___, sand___, magnetism___, water____, a vacuum__, 2

3. The Kinetic Molecular Theory (this is not in the text)
04/03/100
All matter is made of atoms and molecules which are in constant motion except at absolute zero.
Atoms and molecules are extremely small: even a small sip of water contains about 6 x 1023 molecules of water 3

4. Properties of matter depend on the kind of atoms in it
04/03/100
Some features of a substance help us identify it because they are characteristic of that substance: density, specific heat, color, strength, luster, hardness, odor, transparency, state or phase, melting point, boiling point,solubility, attraction to a magnet, etc.
The picture shows chemical reactivity of marble chips (CaCO3). 5

5. Properties are also related to the atomic structure of the substance
04/03/100
The way that the atoms of a substance are arranged will affect the properties: there are three forms of carbon: diamond, graphite and soot.
Diamond silicon graphite and soot 4

6. MATTER HAS 3 STATES OR PHASES
SOLID
LIQUID
GAS

7. 04/03/100
Phases of Matter
Matter can usually be found in one of three phases, or states.
Sometimes it is not so obvious as to what phase a substance is in; glass, for instance, is sometimes considered to be a slow moving liquid 6

8. GAS VOLUME AND PRESSURE ARE RELATED
AS THE VOLUME OF THE CONTAINER DECREASES, WHAT WILL HAPPEN TO THE PRESSURE ?

9. Adding more molecules of a gas to a container increases the number of collisions of these molecules with the sides of the container. How does this effect the pressure exerted by the gas?

10. Gas volume is affected by temperature if the container is expandable and contractible: in the situation below the syringe has a changeable volume. what happens to the volume of the gas when temperature is increased? Decreased?

12. As the pump is adding air molecules to the tire,what is happening to the pressure, volume and temperature inside the tire?

13. PHYSICAL AND CHEMICAL PROPERTIES

14. PURE SUBSTANCES CAN BE ELEMENTS OR COMPOUNDS, BUT NOT MIXTURES
PURE SUBSTANCES CAN BE ELEMENTS OR COMPOUNDS, BUT NOT MIXTURES. 14 KARAT GOLD IS NOT A PURE SUBSTANCE. WHAT DO WE CALL SUCH A MIXTURE?
