Week+4+Notes

1. //Law of Conservation of energy and matter// : matter and energy can not be created or destroyed. We must save them.

2. //Law of Constant Composition// : the stuff or substance that something(an object) is made of, is what its made of.

3. //Unit Values//

1m = 1m 1m = 10dm 1m = 100cm 1m = 1000mm 100m = 1hectom 10m = 1decam deci- 10 centi- 100 milli- 1000

4. //Unit Conversions//

Given - $ 4.25 $1.00 = 4Q's $ 4.25 * 4Q/$1.00 = 17Q's $ 4.25 = 17Q

5. //Scientific Notation//

a. 10^4 = 10,000 b. 100 = 10^2 c. 10^1 = 10 d. 15 * 10^-1 = 15 e. 10^0 = 1 f. -.6 = -6 * 10^-1

6. //Density// D = mass/volume

lighter density then water = lighter density bigger density than water = increase density gases = light density
