Refers to anything that
pertains mass and
space.
Matter
2
Basic unit of matter
Atom
3
The amount of matter
Mass
4
Space that the matter occupies
Volume
5
states that matter is particulate
in nature. This means that matter is made up of tiny particles with
empty spaces between them. The particles, called atoms.
The Kenetic Particle Theory
6
has definite shape and volume. The particles are tightly
packed.
Solid
7
doesn't have definite shapes but has definite volume.
Particles are close with each other.
Liquid
8
both the volume and the shape are dependent with the
shape of the container. Particles usually apart with each other.
Gas
9
is the fourth state of
matter. Formed by
heating and ionizing a
gas, plasmas are made
up of groups of negatively
and positively charged
particles.
Plasma
10
scientist believed there is a
fifth state of matter, the Bose–
Einstein Condensate (BEC). The
name is derived from the name of
Albert Einstein and Satyendra Nath
Bose, who predicted the BEC in
1924. It may occur when atoms
have very similar quantum level, at
temperatures very close to
absolute zero.
Bose-Einstein Condensate
11
are characteristics of a
substance which can be
without changing its
composition. Some examples
of physical properties are
boiling point, melting point,
density, color, odor, hardness,
electrical and thermal
conductivities, tenacity,
elasticity and plasticity.
Physical Properties
12
are characteristics that
can be observed with an
accompanying change in the
chemical composition of the
substance. This is also can be
done by producing matter into
a new form of substance.
Chemical Properties
13
changes
that do not alter the
composition of the substance.
Physical Change
14
changes
involves in the composition of
the substances. Food
undergoes chemical changes as
it is cooked.
Chemical Change
15
a chemical substance that is composed of a particular set of
molecules or ions that are chemically bonded. Two or more
elements combined into one substance through a chemical
reaction, such as water, form a chemical compound. A chemical
compound can be either atoms bonded together in molecules or
crystals in which atoms, molecules or ions form a crystalline
lattice. Pure substance can either be Elements or Compounds.
Pure Substance
16
a component or constituent
of a whole or one of the parts into
which a whole may be
resolved by analysis.
-one of the class of
substances that cannot be
separated into simpler substances
by chemical means.
Elements
17
a pure substance
composed of two or more
elements whose composition
is constant.
something formed by
compounding or combining
parts and elements
Compound
18
a type of matter in which it
is created by linking two or more
different substances and are
physically combined and can be
separated back into its original
substances. This can be further
sub-divide to homogeneous and
heterogeneous mixture.
Mixture
19
a mixture in which the
composition is uniform throughout
the mixture. All solutions would be
considered homogeneous because
the dissolved material is present in
the same amount throughout the
solution. One characteristics of
mixtures is that they be separated
into their components.
Homogeneous
20
unlike with the homogeneous
mixture, it is uniform in composition.
Heterogeneous
21
suspended particles can be seen and are large
enough to be filtered.
Suspension
22
generally classified as heterogeneous, where the
particles are bigger than those of solutions but smaller than those
of suspension.
Colloids
23
particles can be separated mechanically.
Coarse Mixtures
24
is the pouring of the liquid from a mixture to separate the liquid (decantate) from the solid particles.
Decantation
25
pouring of the mixture through a piece of paper (filter paper) which lets the liquid (filtrate) pass through but catches the solid.
Filtration
26
the removal of suspended particles either by sedimentation or coagulation.
Flotation
27
settling of tiny
suspended particles
using a centrifuge.
Centrifugation
28
use of the differences in
boiling points. In a mixture of
two liquids, the liquid with the
lower boiling point boils and
changes into gas first. The gas is
then condensed back to a liquid
(distillate ). This is used to
separate solid particles from the
liquid
Distillation
29
separates liquid mixtures whose components have boiling
points that differ by just a few degrees. This process is used in
petroleum refineries.
Fractional Distillation
30
occurs when simple
seawater is allowed to
evaporate. The salt
crystallizes out. This is not
limited to liquid solutions.
Crystallization
31
is an analytical technique commonly
used for separating a mixture of chemical
substances into its individual components,
so that the individual components can be
thoroughly analyzed. There are many
types of chromatography e.g., liquid
chromatography, gas chromatography,
ion-exchange chromatography, affinity
chromatography, but all of these employ
the same basic principles.
Eleme
Chromatography
32
is a substance that cannot bee broken down into simpler
substances by a chemical change.
Elements
33
Formed when two or more elements combine in a chemical
change. They are substances that can be broken down into simpler
substances only by a chemical reaction.
Compound
34
many numbers used in chemistry are either very large or very
small that the number of zeros become difficult to handle. For
accuracy and convenience, these numbers are written in the form
Scientific Nonation
35
is way of presenting information about the chemical
proportions of atoms that constitute a particular compound or
molecule, using chemical element, symbols, numbers and
sometimes also other symbols such as parenthesis, dashes,
brackets, commas and plus.
Chemical Formula
36
are the simplest form
of notation. They provide the
lowest whole number ratio
between the elements in a
compound. They do not
provide information about the
absolute number of atoms in
a single molecule of a
compound.
Empirical Formula
37
consists of the chemical
symbols for the constituent
elements followed by numeric
subscripts describing the exact
number of atoms of each
element present in a molecule
or a compound.
Molecular Formula
38
identify the location of
chemical bonds between the atoms
of the molecule. A structural formula
is consists of symbols for the atoms
connected by short lines that
represent chemical bonds.
- the arrangement of atoms of
each elements that constitute the
molecule or compound.
Structural Formula
39
properties do not depend on the amount of matter in a sample.
Intensive Properties
40
depend on how much matter a sample contains.
