has definite shape and volume
example
ice
pencil
liquid
loosely
definite volume
do not have definite shape
example
water
alcohol
gas
very loosely
do not have definite shape and volume
exmaple
Water Vapor
Oxygen
plasma

characteristic
most like gas
make up
atoms
characteristic
take up space
has mass
properties of matter
Physical Properties
can be observed or measured
can change without the substance becoming different
types
Intensive properties
Extensive properties
The most important quantitative properties
of matter
mass
measure of the amount of “stuff” in an
object
depends on types and quantity of atoms in the object
measured in grams (g)
conservation of mass
the total amount of mass does not change
The Law of Conservation of Mass
matter can change form or be rearranged
in a close system, the mass of the
reactions must equal the mass of the
products
a chemical equation can shows all mass is
conserved throughout the reaction
magnetism
an invisible force exerted by some types of
matter
temperature
a measure of how hot or cold an object or
substance is
Fahrenheit (°F) or Celsius (°C).
length, width and height
describe the size of an object
meters (m)
size and shape
describe the dimension and form of an
object
volume
describes how much space an object takes
up
Litters (L) or quater
viscosity
a property of matter that is important to
fluids
solubility
describes how well a substance dissolves
into another substance to produce a
solution
density
measurement that reflects how much mass
takes up a certain amount of space
grams/milliliter (g/mL)
conductivity
describe how well an object or substance
transfers electricity or heat
Thermal conductivity
Electrical resistivity
boiling point
melting point
Chemical Properties
describe the chemical makeup of a substance
describe the ability of a substance to change its identity
examples
Reactivity
Toxicity
several important chemical properties of
matter
Reactivity
describes how easily and fast a substance
undergoes a chemical reaction
Corrosion
gradual destruction of an object by
chemical reactions with factors in the
environment
Oxidation
the destruction of matter due to chemical
reactions with oxygen
Tarnish
a thin layer of corrosion that forms on the outside of certain metals such as copper, brass, silver and aluminum
Toxicity
describes the degree to which a substance
can harm living things
Flammability
describes how easily a substance will ignite
or catch fire
Combustibility
describes the how well a substance burns
Radioactivity
refers to the particles released by radioactive atoms. Radioactive atoms make up radioactive matter
pH
a measure of how acidic or basic a solution is
two types of changes matter
physical change
does NOT involve a change in a substance’s
chemical makeup
no new substance is produced
usually reversible
chemical change
involves a change in a substance’s physical
and/or chemical properties
produces a new substance
usually not reversible
Phase change
Definition
Matter can change from one form to
another
A phase change takes place when heat is
added to or removed from a substance.
types
Freezing
Removing heat from a liquid substance
liquid to solid
freezing point
The temperature at which a liquid freezes to
a solid
Melting
Adding heat to a solid substance
solid to liquid
melting point
The temperature at which a solid melts to a
liquid
Condensation
remove heat from a gas
gas to liquid
condensation point
The temperature at which a gas condenses
to a liquid
Evaporation
Adding heat to a liquid substance
liquid to gas
boiling point
The temperature at which a liquid
evaporates to a gas
Sublimation
A solid directly change into a solid
example
Dry ice is solid carbon dioxide. When left at
room temperature, dry ice sublimes into
gaseous carbon dioxide.
Deposition
A gas directly change into a solid
example
On very cold winter mornings, water vapor
in the air deposits as tiny ice crystals on the
leaves of plants.
heating
adding thermal energy to a substance
heated
melts
solid to liquid
evaporation
liquid to gas
cooling
removing thermal energy from a substance
cooled
freezing
liquid to solid
condensation
gas to liquid
