General Properties of Matter | mass / density / volume / weight |
mass can be measured in units called | grams |
as mass increases what happens to inertia | it increases |
weight is | the response of mass to the pull of gravity |
unit used to measure volume | mL / cubic centimeter |
Density = | m/v |
Why does ice float in water | it's less dense |
the density of water = | 1 g/ml |
where would you weigh the most, on the moon, outer space, or the earth's surface? | earths surface |
an object that floats has a density less than | 1 g/mL |
the constant amount of matter in an object determines its | mass |
the resistance of an object to a change in its motion | inertia |
burning paper is an example of what type of change | chemical change |
have a definite shape and volume | solids |
mass,weight,color,shape,texture, hardness,volume,and density are all what type of property | physical property |
all changes in phases are | physical changes |
chemical properties describe how a substance can | change into another substance |
resistance of the liquid to flow is | viscosity |
changing from a solid to a gas | Sublimation |
change in which NO new kinds of matter are produced | physical changes |
particles from what phase are able to expand without any limit | gases |
changing from a gas to a liquid | condensation |
changing from a liquid to a solid | freezing |
when tiny particles are packed tightly together they make up a | solid |
example of a substance that sublimes | dry ice / snow |
very high energy PHASE of matter not naturally found on earth | plasma |
cutting your grass is an example of what type of change | physical |
definite volume but no definite shape | liquid |
Boyle's Law states , when the pressure on a gas increases the volume will | decrease |
When gas leaves the surface of a liquid, the liquid | evaporates |
particles of a liquid are | fairly close together |
