MatterMatterDefinition: anything with the characteristics of mass and volume
A human is considered matter because they take up space
(volume) and they have mass.
Not Matter• Definition:
something that is unrelated to matter, and it itself is not categorized as matterThoughts do not take up
space (volume), as well it does not have mass, it is
merely a concept that someone thinks up, meaning
it is not of matter
Pure Substance• Definition:
matter that has only one type of particle
Sugar is an example of a pure substance, as it has
only one type of particle. * Pure substances are
composed of elements and compounds
Element• Definition: a pure substance that has only one kind of particle, substance cannot be any simplerSilver is a type of pure substance which is an
element, there for it only has one kind of particle. Pure silver necklaces like these are a good example
of an element.
Compounds• Definition: a
pure substance that has two or more elements that makes up one type of particle
Salt is a combination of the elements sodium and chloride, which makes it composed of two different elements which
equal one type of particle
Mixtures• Definition: any
substance that has two or more pure substances
The substance that makes a T.V screen glow is made of a mixture of metal compounds
to create the proper wavelength. One of the pure
substances include Phosphors.
Heterogeneous Mixtures
• Definition: a type of mixture in which its components can be easily seen
Soda is a type of heterogeneous mixture
because the carbon dioxide is visibly seperated from the
liquid itself.
Homogenous Mixtures• Definition: a type
of mixture in which its components are well blended that it seems as one to the human eye Grape wine contains mixtures
of alcohol, grape juice, sugar and many other components, but it is so well mixed that the components can be only seen
as a red liquid.
Mass• Definition: the measure of the number of matter contained in an object, unlike weight
These two beakers are of the same shape and
size, however they weigh differently,
meaning even if two objects are similar, their mass may be different
Volume• Definition: the
amount of space an object takes up
Without me or the clothes, the closet is an empty space, but
once the clothes and I are placed within, we take up the once available space in the closet, meaning we have
volume.
Density• Definition: mass
per unit volume of a substance ( ex: its ability to float)A person swimming is an example of density
as a person needs enough oxygen in
their body to become less denser (lighter)
than water
Viscosity• Definition: the
property of a fluid that goes against the force in which causes the fluid to flow
Face powder is contains miniscule types of fluid,aside from the powder itself, which depends on viscosity to be
applied properly onto the face
StateStateDefinition: the states in which matter can be found, solid, liquid and gas
An ice cube
is water in a
solidi-fied
state as it
is fro-zen
Water, is
water in a
liquid state as it flows easily
Steam is a gaseous state of
water as it is water vapor
ConductivityConductivityDefinition: ability of a material to conduct heat or electricityA
boiling pot can
absorb heat and
use it to
cook, mean-ing it has
conductivity
A wire is used to transmit
electricity
as it is made of metal wiring
meaning it has
conduc-tivity
Physical ChangesPhysical ChangesDefinition: the changing of the form or state of a substance but not the substance itself
Crumpling and
ripping the tin foil changes its form, but not
itself as it is still tinfoil
neverthe-less
The part of the paper with
absorbed water
changes its form, as it is softer,
however it is still paper
Chemical ChangesChemical ChangesDefinition: a chemical reaction happening within a substance which changes it into a new substance with different propertiesOnce the
paper is burned,
its propertie
s or compo-
nents are changed, giving it
new blackene
d characteri
s-tics
Once the egg is
fried, it becomes
cooked and no longer liquid, its
components are
changed during the frying, thus the name,
fried eggs.
