2000 lb
2. 1 Cup = ? fl oz
8 fl Oz
3. Dimensional Analysis
Using the graph/chart to set up the problem
4. 1 cup = ? Tablespoons
16 T (tablespoons)
5. Measured
Using instruments to measure
6. Exact Number
No instruments used only counting and by definition
7. 1 T = ? t teaspoon
3 t (teaspoon)
• Zero Before
• Nonzero numbers = Not SIG
• 0.40907 cm = 5 SF
• 0.00078 dm = 2 SF
9. 1 lb = ? Oz
16 Oz
10. Trailing Zero
• After nonzero number with decimal = SIG without decimal = not SIG
• 8800 lb = 2 SF
• 8800.050 = 7 SF
11. English measurement converstions
• Mass - (Equality) 454g = 1 Lb
• Volume - (E) 946 mL = 1 qt
• Length - (E) 2.42 cm = 1 in
12. Centi
1g = 100cg
13. 1 gal = ? qt
4 qt
14. Deci
1g = 10dg
15. 1 yrd = ? ft
3 ft
16. 1 pt = ? cups
2 cups
17. Conversions Factors
1g =100cg  1g/100cg = 100cg/1g
18. 1 ft = ? in
12 in
19. Micro
1g = 1,000,000 ug
20. Kilo
1 Kg = 1000g
21. Chemistry & Chemicals
Can make Chemicals "synthesized" in the lab. Composed of elements same composition no matter what.
22. 1 qt = ? pt
2 pt
23. Volume: ? mL = 1 qt
946mL
24. Metric System - Base Units
• Meters (m) [Length]
• Liters (L) [Volume]
• Grams (g) [Mass]
• Celsius *C [Temperature]
• Seconds (s) [Time]
25. Mass: ? g = 1 Pound (lb)
454 g
26. Mili
1g = 1000 mg
27. 3 ft = ? in
36 in
28. 1 mi = ? ft
5280 ft
29. Pure Substance
Matter with a fixed composition (does not change)
30. Two types of Pure Substances
• Element - C, N, O, Ca, Fe, K, etc.
• Compound - 2 or more elements
31. Mixture
2 or more substances with a variable composition
32. Two types of mixtures
• Homogeneous - uniform appearance. Salt water, gasoline.
• Heterogeneous - contains layers. Italian salad dressing, water + sand
33. Physical Properties
Characteristic that identify matter color, density, freezing point, and specific heat.
34. Physical change
Appearance changes, but not the composition. Ice, water, steam, aqueous
35. Chemical Properties
Ability to change into a new substance. Its flammability, explosive, tarnish (turns into a black substance), corrosive (rust)
36. Chemical Changes
Compounds combine to make a new substances.... chemical reaction
37. Energy (6 types)
• L - Light energy
• N - Nuclear energy
• C - Chemical energy
• H - Heat energy
• E - Electrical energy
• M - Mechanical energy
38. Potential engery
• Position - The higher more energy
• Stored - in the chemical composition of the substance
39. Kinetic Energy
• Energy from movement. Explosive, cars, temperature.
• More KE, more movement.
40. 1 cal = ? J
4.184 J
41. *C -> *F
TF = TC (1.8) + 32
42. *F -> *C
TC = TF - 32/ (1.8)
43. K -> *C
T*C = TK + 273
44. *C -> K
TK = T*C - 273
45. Specific heat
• AMT of heat needed to raise the temp of 1g substance by 1*
• Lower the SH the easily the change in temperature occurs.
46. Equation for SH
• SH = cal or J/ g (*C)
• SH = Heat/ mass (^T)
47. SH, Finding the Heat
Heat = SH (mass) ^T
48. Energy values from food: Carbohydrates, Proteins, Fats
• Carbohydrates = 1 g carb/4 kcal = 1 g carb/4 cal
• Proteins = 1 g Pro/4 kcal = 1 g pro/4 cal
• Fat = 1 g fat/ 9 kcal = 1 g fat/ 9 cal
49. Changes in State, physical state
Change is due to loss/gain of energy
