Q

water has a density of __ g/ml OR __ kg/m^3 OR __ pounds/gallon

A

1.0 g/ml OR 1000 kg/m^3 OR 8.33 pounds/gallon

23
Q

specific gravity is the ratio between and object’s density and the density of water

A

any substance with a spec grav greater than 1 is more dense than water
spec grav less than 1 is less dense than water

24
Q

can these guys possibly be violinists

A

charles, temp, gay-lussac’s, pressure, boyles, volume

25
Q

gay-lussac’s law

A

if volume remains constant, pressure is directly proportional to temperature
when the temp of a gas increases in a solid volume container, the pressure increases proportionally
think of bringing an E tank from a cold loading dock in the middle of winter to a warm OR, the pressure will increase

26
Q

boyle’s law (upside down B)

A

if temperature remains constant, pressure and volume are inversely related
if temp remains steady, halving the volume where the gas is doubles the pressure
like squeezing the ambu bag for susan boyle

27
Q

charles’ law, the 18th century hot air balloonist

A

if pressure remains constant, volume is directly proportional to temperature
thus applying heat to a gas increases the volume it will occupy

28
Q

Farhenheit to Celsius

A

F to C, minus 32, x 5, / 9

29
Q

Celsius to Fahrenheit

A

C to F, x 9, / 5, +32

30
Q

Great many kids have dropped (over) dead converting metrics multiple numbers profess

A

Giga mega kilo hecto deka (unit) deci centi milli micro nano pico

31
Q

After PEMDAS, solve from _ to _

A

left to right, the same way as you read a book

32
Q

multiplying or dividing TWO POSITIVE numbers OR TWO NEGATIVE numbers gives a __

A

positive
-1 x -1 = 1
1 x 1 = 1

33
Q

multiplying or dividing a positive number and a negative number gives a __

A

negative
-1 x 1 = -1
1 / -1 = -1

34
Q

to solve for a variable

A 
apply the inverse operation
x / 5 = 20  the inverse of division is multiplication so therefore multiply BOTH sides by 5
(x/5) x 5 = 20 x 5
x = 100
(100/5) x 5 = 20 x 5
35
Q

apply PEMDAS except when the equation involves addition and subtraction as well as multiplication and division. In that case reverse the order of operations

A

F* = 10C x 1.8 + 32
do the addition/subtraction first F - 32 = 10C x 1.8
then do the multiplication and division F - 32 = 18
now apply the inverse of -32 to solve for F* = 18 + 32
F* = 50
10 C* = 50*F

36
Q

to solve for a square root on one side of the equation

A

square both sides of the equation to cancel it

37
Q

logs
10^2 = 10 x 10 = 100 how many times do you multiply a number to get the square? two
log10 ( 100 ) = 2

A

log10 (100) = x
how many times do you have to multiply 10 by itself to get 100? two
x = 2

38
Q 
antilog
the antilog (2) = 10^2 = 10 x 10 = 100
antilog (3) = 10^3 = 10 x 10 x 10 = 1000
A

antilog (4) = __

39
Q

negative exponents equal the reciprocal

A 
2^-1 = 1/2
3^-1 = 1/3
40
Q

any number raised to a zero power equals 1

A 
3^0 = 1
4^0 = 1
41
Q

to multiply two numbers with exponents, remember to turn the x thirty degrees to a + and then add the exponents

A

1^2 x 1^3 turn the x a little into a +
2 + 3 = 5
1^2 x 1^3 = 1^5

42
Q

to divide two numbers with exponents, remember to turn the / thirty degrees to a - and then subtract the exponents

A

1^2 / 1^3 turn the / a little into a -
2 - 3 = -1
1^2 / 1^3 = 1^-1

43

51
Q

Mega

A

1 x 10^6

M

52
Q

kilo

A

k

53
Q

deci, centi, milli, micro, nano

A

1 x 10^ -1, -2, -3, -6, -9

d, c, m, mu, n

54
Q

mcg are to grams as uL (mu = micro) are to liters
1,000,000 mcg = 1 gram
1,000,000 uL = 1 liter

A

10^-6 liters = 1 uL (micro liter)
