10^9

G giga


10^6

M mega


10^3

k kilo


10^1

d deci


10^2

c centi


10^3

m milli


10^6

u micro


10^9

10^12

p pico


1 kg = 1000g = 1x10^3gram

mass


Volume is length(m)CUBED
1cm^3 = (1x10^2m)^3 = 1x10^6m^3 
volume


A liter is the volume occupied by one cubic decimeter

liter


One liter = 1000 milliliter(L)
mL 
mL


1 mL = 1 cm^3
One milliliter = one cubic centimeter 
cubic centimeter


Density is the mass of an object divided by its volume
D = m/v 
define density


Density is an intensive property. As such, does not depend on teh quantity of mass present. The ratio of density always remains the same for a given material  regardless of quantity.

density  an intensive property


SI unit for density is:
kg/m^3 Common unit is grams/milliliter: g/mL (solid and liquid density) 
SI unit for density


Fahrenheit scale:
freezing is 32F boiling is 212F 
Fahrenheit


Celsius scale:
freezing is 0C boiling is 100C 
Celcius


Kelvin scale: the official SI Unit for temperature. Absolute temperature scale.
0K is lowest theoretical temp 
Kelvin scale


The size of a DEGREE on the Fahrenheit scale

5/9 of a degree on the Celsius scale


Formula to convert Fahrenheit degrees to Celsius
?C = (F32F) x 5/9 
?C = (F32F) x 5/9


Formula to convert Celcius to Fahrenheit
?F = 9/5 x C + 32F 
?F = 9/5 x C + 32F


T/F:
One degree of Celcius is equal in magnitude to one degree of Kelvin 
true


What is absolute zero on the Kelvin scale = on the Celsius scale?
273.15C 
273.15C


Convert Celcius to Kelvin:
?K = (C + 273.15C)x 1K/1C 
?K = (C + 273.15C)x1K/1C


Regardless of magnitude, all numbers can be expressed as:
N x 10^n 
N x 10^n


Scientific notation:
If the decimal is moved to the left, it is a ____integer. If to right, it is a _____interger 
Left positive integer
Right negative integer 

T/F
In significant figures, it is assumed that the last digit is understood to be "uncertain" 
T


Rules for Significant Digits:
 Any digit not a zero is significant.  Zeros between nonzeros significant.  Zeros to left are NOT significant.  Zeros to right significant  Trailing zeros (after last nonzero digit) may/may not be and needs scientific not. 
significant digit rules


Add/Sub, answer cannot have more digits to the right of the decimal point than either of original numbers

T


Roundoff procedure:
 Drop digits if less than 5  Equal or greater than 5, round up 
T


Mult/Div: #of signficant figures determined by the original number that has smallest # of signficant figures

T


Exact numbers obtained from definitions (eg 1ft = 12 in), or by counting # of objects  considered to have an infinite number of significant figures

T


Accuracy:
How close a measurement is to the true value of the quantity measured. 
Accuracy


Precision:
How closely two or more measurements of the same quantity agree with one another. 
Precision


Dimensional Analysis = Factor Label Method
Uses relationships between different units to express the same physical quantity 
Dimensional analysis


Grams to Milligrams:
1x10^3 = 1 mg 
1000 mg = 1 gram
