QuestionAnswer
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
