32
mass is
the amount of matter in an object
33
kilogram = ___ lbs
2.2
34
mass of large obj
kg
35
mass of small obj
gram
36
mass of smaller obj

37
density
how much mass is in a given volume of an object mass per unit volume of an object
38
formula to find density
density = mass / volume
39
unit of measure for temperature
celsius 100 ^ boiling point 0^ freezing room temp 21^ norm body temp 37^
40
in a conversion fraction the numerator always ___ the denominator so the fraction always equals ___
= | 1
41
to convert one metric unit to another you must
multipy the given value by the conversion factor
42
to convert you place units to be converted in what part of the fraction
denominator = units to be converted
43
steps of dimensional analysis
id given units / units to be converted create a conversion factor denominator of conversion factor is the same unit that is to be converted cross multiply so that units to be converted ends up as the numerator
44
what two liquids are commonly used in thermometer
:) | alcohol or mercury
45
meniscus
curve of liquid in graduated cylinder - point at which liquid is measured mm
46
general properties of matter
mass weight volume density
47
mass can also be described as
inertia
48
inertia
resistance of an object to changes in its motion Galileo
49
weight
exists because of objects mass, responce of the objects gravitational pull
50
units to express density
g / cc g/ mL
