2. EVERYTHING!!!! Anything that takes up space and has mass

3. A form of matter that has a definite composition All substance is matter, but not all matter is a substance How can that be???

4. Homogeneous mixture – A mixture that has the same properties throughout. Heterogeneous – A mixture in which substances are not uniform

5. Water (H2O) OIL AND WATER KOOL-AID US IN THIS CLASSROOM!!!!

6. A substance that cannot be broken down any further.

7. The basic building block of an element

8. A substance composed of atoms of two or more elements. H20 –Water C02 – Carbon Dioxide NaCl – Sodium Chloride (table salt)

9. 1) Johnny Boy desires to see why his clothes sometimes fade more than other times when he is washing his clothes. He buys three different detergents and will record the results. The detergents are what component of the scientific method? 2) Define the following as an element, compound, heterogeneous, or homogeneous mixture: 1) salt water, 2) iron and sand, 3) oil and water, 4) Oxygen, 5) Water, 6) Hydrogen.

10. Solid, Liquid and Gas Gas molecules are the most spread out, they are closer together in liquids, and most compact (or dense) as a solid THE COMPOSITION NEVER CHANGES!!!

12. Physical Property – An observation of a substance that can be observed without transforming the substance into another substance Basically, the observations as is

13. Chemical Property – Any property of a substance that cannot be observed unless the substance undergoes a chemical change. Basically, you cannot observe a chemical property without changing it.

14. Conversion of Water to Ice Mixing of Water and Salt Boiling point of lead Hydrogen combining with Oxygen to form water

15. Extensive – Depends on how much Matter (Mass, Volume, length) ADDATIVE Intensive – Does not depend on how much Matter (density, temperature) NOT ADDATIVE

16. Extensive – a number that pertains to amount. Like how many, how heavy, or how long. Intensive – a number that pertains to a character. Like how hot, or how dense

17. Your Body temperature Your height Your weight The density of ice

18. Density = Mass / Volume D = m / v Remember, that density is intensive. Therefore does not depend on the mass.

19. A piece of gold ingot has a mass of 301g and volume of 15.6 cm3. What is the density???

20. d = m / v d = 301 g / 15.6 cm3 d = 19.3 g/cm3 YOU TRY IT!!!! The density of Mercury at room temperature is 13.6 g/mL. What is the mass of a sample of mercury with a volume of 5.50 mL???

21. d = m / v 13.6 g/mL = m / 5.50 mL (13.6 g/mL) (5.50 mL) = m 74.8 g = m

22. Fahrenheit (F°) Celsius (C°) Kelvin (k) Kelvin is an absolute number K = C° + 273.15 C° = (F° - 32°) X 5/9 F° = 9/5 X (C°) + 32°

23. Convert 31°C = ______k 435°F = _____C° -269°C=_____F° 234.3k = _____C°
